A glitch (also known as a bug) is a fault in a program that causes it to function improperly. The severity of glitches can vary. The most common glitch is the recurring graphical stretching glitch, which causes models to stretch, but has no impact on the gameplay. More severe glitches include the infamous Falador Massacre, where a player was able to attack other players outside of a player-versus-player area.
Abuse of glitches is a direct breach of the "bug abuse" rule under the honour section of the rules of RuneScape. The punishment for guilty parties varies depending on the particular glitch, and the degree to which it was abused. Minor graphical glitches generally go unpunished, while major abuse (such as what occurred in the partyhat duplication glitch), may result in a permanent ban.
Jagex has recommended that players who find a glitch in RuneScape should report it to Jagex immediately via the "Submit a Bug Report" interface accessed by clicking on the button located on the chat box.
The Falador Massacre was an infamous glitch where a player was able to attack other players after a glitch involving player-owned houses was discovered, and proceeded to attack many players in the Falador area until he was stopped.
The noclip glitch allowed a pair of bug abusers to walk through barriers in RuneScape, nearly entirely unrestricted.
25 February 2009 crashEdit
In February 2009, there was a bug where if your chat was on, seeing the "µ" character in the chatbox made the game crash. It was abused during player-versus-player combat.
Partyhat duplication glitchEdit
The partyhat duplication glitch is one of the most famous glitches in RuneScape, where a third-party program was used to manipulate the game engine, allowing the creation of items.
9 June 2009 game engine update glitchEdit
The game engine was significantly rewritten on 9 June 2009, causing a multitude of bugs to crop up all across RuneScape. Glitches ranged from nonoperational bank booths to ranged attacks only working when standing right next to a foe.
Penguin Hide and Seek glitchEdit
The Penguin Hide and Seek glitch allowed players to spy the same penguin multiple times, allowing them to get unlimited penguin points, which could be exchanged for experience.
PvP drop potential glitchEdit
When RuneScape had PvP worlds, a glitch allowed them to be manipulated, by using a beast of burden on a free to play, then dying multiple times, fooling the game with the wealth you have carried, before returning to a members world for kills with high drop potential.
Bolt duplication glitchEdit
The bolt duplication glitch was a glitch where the player could enchant multiple bolts out of only a single bolt, vastly multiplying their profit.
Equipable knife glitchEdit
Runecrafting experience in Dungeoneering glitchEdit
Guthix rest tea glitchEdit
The Guthix rest tea glitch caused the drink to heal the player entirely, as well as remove poisoning, and restore run energy.
Ring of wealth glitchEdit
Dropping destroy-only items and pets glitchEdit
A feature that allowed items to be dropped while banking caused a glitch, allowing items that normally could only be destroyed, as well as pets, to be dropped instead.
Rat Pits MassacreEdit
Upon release of the updated graphics for Burthorpe, the mindspike reward from the Troll Warzone tutorial was able to kill almost any normally unattackable NPC instantly, although they only dropped bones.
Kennith's Concerns death glitchEdit
The Kennith's Concerns death glitch occurred when a player died when sneaking past the guards in Kennith's Concerns. Normally, players could not die during this part of Kennith's Concerns, but some players were able to kill themselves using Nitroglycerin, which allowed them to go anywhere in RuneScape in this position. Upon death outside of the mines however, the player would simply end up back in the mines, their items intact.
Invisible items glitchEdit
After the release of Z-buffering, items would occasionally be rendered underneath the floor. The items could still be clicked and picked up, but were effectively invisible. When the release of Social Slayer came out some items in your inventory or bank were invisible.
Smuggling Dungeoneering items glitchEdit
Several similar glitches have allowed items normally restricted to the dungeons of Daemonheim to be smuggled outside, using either teleports or a beast of burden. Currently all dungeoneering weapons disintegrate if equipped outside of Daemonheim.
Attacking players in the Tower of Life glitchEdit
Upon release of the Tower of Life, the basement's placement directly below the wilderness allowed players to attack each other.
Crucible Money Making GlitchEdit
The bug caused Jagex to do a complete shutdown of the game, making all worlds offline. A large number of players were banned for abusing this glitch.
Money Pouch GlitchEdit
When the Crucible Money Making Glitch referenced earlier, above, was fixed, a glitch with the bank PIN on the money pouch let players quickly enter the Crucible Arena, paying their fee, and exit, going to the bank to refill their money pouch to maximum capacity, and getting their fee back. What resulted was two stacks of their fee repaid dropping to the floor, duplicating what they were to normally be paid out only once. This could be done repeatedly. This glitch also was able to be performed in the duel arena using a similar method and was patched on the same day. This is also one of the few glitches in which Jagex publicly posted the names of the abusers on main newsfeed. Estimates on the amount of gold duplicated vary from 800 billion to 7 trillion gold. Prior to being virally leaked, people were known to have multiple scripts repeating the glitch since at least 20 June. It was patched on 5 August, 2012, and all accounts were rollbacked to 3 August 2012.
Rogue Botwatch Bans GlitchEdit
While updating their Botwatch macro detection systems on 27 September 2012, a heuristic used during its testing phase had been accidentally enabled. This resulted in unappealable permanent bans being placed over 40,000 players. Some of these players also reported receiving (in some cases multiple) false macroing warnings in-game, as well as dropped items vanishing instantly. Less than an hour after the Botwatch issue was discovered, Jagex fixed it and released an apology to the affected players. Every single ban and offence directly related to the glitch was then manually removed and those affected by the glitch were also given 20 free spins on the Squeal of Fortune as a gesture of goodwill, although no items that were lost due to people dropping them were refunded.
Scrimshaw of Cruelty massacreEdit
Around midnight 20 January 2013, players discovered that using the Scrimshaw of cruelty in PvP minigames would let the poison effect stick after the minigame ended. This resulted players in minigames such as Soul Wars and Castle Wars becoming poisoned and eventually dying.
Many forum posts were created to warn about the glitch, as well as people demanding a rollback after losing high valued items due to being killed.
Jagex patched the glitch within two hours after it gained attention from the community, but there have been sightings of bots and players getting killed by poison in minigames prior to this event.
Can't loot BoB familiarsEdit
After the 20 November 2013 update, including changing the interface for BoB, using a pack pig familiar to store items would not allow for items to be manually withdrawn after the first 4 items. The items could be still be withdrawn by using the 'Take BoB' option, but only if enough inventory was free to withdraw it all. Items would also not move to the front of the BoB inventory as they previously had, but would remain in the same position.
Royal Rhino GlitchEdit
If a player uses the Royal Rhino's storage facility and dismisses the rhino, when summoning the next BoB players will be notified that their familiar is about to vanish in 30 seconds. After 30 seconds, any items in the BoB will drop onto the ground, although the familiar will not vanish yet.
Graphical stretching glitchEdit
Graphical stretching glitches, where a part of a model stretches in a way not intended, are one of the most common types of glitches in RuneScape.
Minimap glitches are common in RuneScape, including black or white backgrounds on the minimap, black sections, or failure to display the minimap all together.
Dungeoneering timer glitchEdit
The floor timer in Dungeoneering displays a random time, measured in hours, rather than the actual time of the floor in progress. After the timer goes past 23:59:59, it loops back to 23:00:00.
