Glitch

A '''glitch''' is a flaw/unintended effect within a game. [[RuneScape Classic]] has seen many glitches; here is a page where they are documented.

=='''Fixed Glitches'''==
==='''Knife Glitch'''===
:''Main article: [[Knife Glitch]]''

==='''Great Party Hat "Dupe"'''===
:''Main article: [[Great Party Hat Dupe]]''

==='''Packet Construction Glitches'''===
With the use of packet construction through AutoRune, not only were items created, but people could also:
*Attack and kill themselves in the [[Wilderness]]
*Make themselves invisible at the [[Make over mage]]
*Attack any [[non-player character]]
*Cast Spells without [[runes]] or a target

==='''Fatigue Glitch'''===
A flaw during server maintenance caused all Beds and Sleeping Bags to not work in all non-veteran servers. It was fixed shortly before the second reopening.

==='''Max Cash locking out accounts'''===
Players who gained over the maximum 32-bit integer limit (2,147,483,647) coins would be disconnected from the game and unable to login. Anyone who deposited over said limit into the bank found themselves unable to open their banks as they would immediately disconnect. It was finally patched on 16 February 2015. Any coins deposited over the limit now simply vanishes.

=='''Unfixed'''==
==='''Infinite Zombie Spawn'''===
* Normally, a [[Necromancer]] would only spawn 7 zombies. But if a player kills the second [[Necromancer]] without killing the spawns, then the first [[Necromancer]] will be able to summon 7 more until the player stops doing so.

=== '''Water World Glitch''' ===
* Occassionaly, logging into RuneScape will cause the game to load with all the ground tiles replaced with water tiles. This is rather rare, and seems to be especially prone to happening when connecting with a slow/unreliable internet connection. It is impossible to move around normally, as clicking on any water tile does not result in motion to that tile. Instead, the player may only move by interacting with non-ground objects, such as trees or NPCs. It is possible to train skills while this glitch is active, provided that the player can access the areas needed to train the skill. It seems to last until logout.

==='''Crash Bug'''===
* A flaw in which if an entity is examined after it is removed, the game crashes. This is caused by the rewrite of the action system in [[2009]]-[[2011]], and can make [[Player Killing|PKing]] much more risky.

==='''She-Male Bug'''===
* There are several versions of this bug. The first was to equip a [[Rune Plate Mail Body]] as a bearded man, then change the item into a [[Rune Plate Mail top]]. The second was through the use of Auto-Rune.

==='''Death Bug'''===
The death bug is a humorous, but useless glitch in which a player dies from poison while interacting with an NPC/Object. If timed correctly, the player would die and the options to continue an interaction/conversation would persist. Known effects include:
*Forced teleportation
*Bank in wrong location
*Complete Quests in wrong locations
*Store interface at wrong location
*Clone certain NPC's

==='''Gnome Ball Smuggle'''===
An oversight in which [[Gnome Ball]]s could be taken out of the [[Gnome Ball (minigame)|minigame]]. Methods include:
*[[Telegrab]]
*[[Teleport]]
*Shoot

==='''Minor glitches'''===
*[[Merlin]] stays trapped in the [[Giant crystal]] even after the [[Merlin's Crystal]]
*[[Sinclair Mansion]] [[roof]] stays hidden even when player is outside the mansion between [[hedge]]s
*The game contains too many spelling errors to list.
*Certain guards such as the ones near [[Fight Arena]] can be pickpocketed despite lacking said option.
*Experience is sometimes spontaneously rewarded to players when moving to certain areas. Usually combat.
*False (and old) [[death]] message is displayed even though player has not died
*A [[trade]] screen appears out of nowhere and player is shown to be trading with ''null''
*Actions involving heavy clicking sometimes mess up, causing the game to not respond along with the following:
**Add random names to friends/ignore list
**Turn prayers on/off
**Disconnect
**Move to random squares
**Drop random items
**Shows the makeover mage interface (won't actually allow you to edit character)
*[[Crystal chest]] can get stuck open

'''Fatigue training'''
*Because of an oversight in the way the fatigue system works, it is possible to gain experience in [[melee]] skills without gaining [[hits]] experience through [[fatigue training]].

'''Removing objects with Charge'''
*By casting the [[charge]] [[spell]] while standing on the root position of a piece of [[scenery]] (its cyan dot on the mini-map), it is possible to remove the object. This can be done with [[sign]]s, [[fern]]s, [[doors]] which take up more than one tile, and probably some other objects. This can be fixed by logging out and logging back in to make the object appear again.

'''Unattackable Players in Wild'''
*When using a specially crafted 3rd-party client players can send duel requests in the wild. This allows players to fight other players not within their combat level in the wild.
*When dueling in the wild a player can cast magic spells on players not in the duel. This was typically done using tank mages. Players could duel a friend on another account and cast god spells on other players in the wild leaving the player not in the duel helpless.
