this story is not particularly crazy in the scope or size of it, but its definitely an example of breaking a game in a significant and strange way so i was playing world of warcraft with one of my female friends, and it was after the warlords of draenor expansion had released, this expansion featured the ability (more like inevitability) of building and growing your own garrison, which was like a miniature version of the towns you might build in the original RTS warcraft, certain buildings did certain things for you, and because it was basically the hub of your adventures in that expansion it had its own hearthstone. if you are unfamiliar with world of warcraft a hearthstone is normally an item you get pretty much at the beginning of the game that allows you to pick a tavern in a town or city as your "home" and teleport back there at will, with an hour long cooldown. the garrison you acquire and upgrade however has its own unique hearthstone that teleports you only back there, to your own garrison. well my friend had the expansion but hadn't yet done the quest to get her garrison or even entered draenor normally, she basically just came to my already developed garrison and talked to the NPC that gives out the hearthstone for it if you don't have one. at some point i wanted her to come to my garrison to see something i wanted to show her and she reflexively activated the hearthstone that was keyed to -her- garrison, the garrison that didn't exist yet (and its instanced so that detail is kind of important). she ended up teleporting into the alterac valley battleground (also instanced and impossible to enter without entering a queue and having that queue fill up with other players, and impossible to stay in after the match is up, normally this is an ironclad situation, you get in, fight, win/lose then are forced to leave) it seemed that by activating a hearthstone for an area that essentially doesn't exist, she ended up teleporting to the very first cell in the list of cells that could be teleported to, i assume this because Alterac Valley according to the dewey decimal system would go first in the list of places she could have ended up at, to make matters weirder we also figured since the level cap was 90, she more than likely also ended up in the alterac valley instance for lower level players (10-14 battlegroup). she was killed immediately by guards which we thought was strange, until we realized that not only had she broken into an instanced battleground that wasn't currently in use for any kind of pvp, she had teleported into the OPPOSITE faction's spawn room, killed on sight, and then spawned outside of the vanilla entrance portal for the battleground as if she had died in a dungeon and needed to run back in to resurrect herself, she ran back into the portal and resurrected back outside the portal. we theorized after the incident that if she had accidentally done this and ended up in one of the instanced 10-14 level battlegroups that was in use, its possible she could have slaughtered all of the enemy team before the match even started, especially since the spawn room in battlegrounds nowadays feature an no mana cost buff that lasts until the battle actually starts, allowing any ability to be cast free to allow for pre-battle buffs. she could have griefed 40 enemy players just by showing up in the wrong place at the right time. nowadays since the level cap is no doubt 100, doing this (if it hasn't been fixed) would more than likely result in showing up into a mob of angry, pvp geared level 100's, and its worth mentioning that she only ended up the enemy one more than likely because the spawn points are tagged as alliance and horde in their respective areas, we are horde, but alliance again, goes first because of the dewey decimal system, so theoretically an alliance player could have done this and aided their lower level comrades in battle, and could have secured a very easy victory right before getting a perma ban for what looks like hacking.
