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.

In extremely rare cases, a glitch might cause Jagex to do a complete shutdown of the game (which has happened in the past) making all worlds offline, followed by banning the players who are abusing such a glitch or rolling back the game state to a previous point.

Jagex view on glitches

Prior to 24 April 2018, Jagex upheld a strict policy of no items returned that were lost from glitches; however, after the World 347 Glitch, they "restored" items lost from the glitch with the form of bonds (as well as restoring experience). Untradeables were not returned.

On 7 June 2018, Jagex stated that they previously set a precedent with the handling of the World 347 Glitch and aimed to restore players' accounts when losing items or experience to glitches if Jagex were completely to blame.[1]

Rules on bug abuse

Abuse of glitches is a direct breach of the "bug abuse" rule as stated under Rule 4 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 may result in a permanent ban.

Jagex has recommended that players who discover glitches in RuneScape should report it to Jagex immediately either in-game or via the "Submit a Bug Report" option on the RuneScape website.

Noteworthy glitches

World 347 glitch

Main article: World 347 glitch

After switching servers for scheduled maintenance on 24 April 2018, the world 347 was given Deadman Mode status without forcing players to log out first. This resulted in players losing items and stat reductions, as well as accounts with game-breaking attributes.

Theatre of Blood glitch

Upon release of the Theatre of Blood, there was a glitch where the player holding the Dawnbringer who died would drop another item in their inventory, while the game was meant to drop the Dawnbringer.[2] In one instance, the player was an ironman whose Armadyl chestplate was picked up by their teammate, and as they could not trade it back, Jagex offered to swap the item to its owner.[3]

Coin pouch glitch

Main article: Coin pouch glitch

On 12 July 2018, a game update added coin pouches to Old School RuneScape. A short time after the update, a major bug was discovered where stackable items would convert to a max cash stack (2,147,483,647) on death.[4] The game was taken offline and was rolled back to a previous state.[5]


  1. Mod Sween. Just lost my only armadyl chestplate due to a bug in ToB, kept this instead (Reddit). “With the issue that affected Deadman we set a precedent of attempting to restore accounts to the best of our ability if any sort of loss was caused by an action within our control.”*
  2. Mod Kieren. Just lost my only armadyl chestplate due to a bug in ToB, kept this instead (Reddit). “The staff is supposed to drop instantly on death so other players can use it should you have died; if it was found in your inventory we inadvertently dropped a different slot to the one the staff was in.”*
  3. Mod Ayiza. Just lost my only armadyl chestplate due to a bug in ToB, kept this instead (Reddit). “We have so far had two confirmed instances of this occurring, and in one instance (this one), a player has lost an item due to no fault of their own. This item went to another member of the party. We have since removed that item from them and will be returning it to the player who initially lost the item, as they are an Ironman.”*
