Basically: The game is Cataclysm: Dark Days Ahead. For those not aware of how the game works, it operates in turns, with every character and monster getting 100 turns to perform actions before the other creatures in the game get theirs. Each action takes a set amount of turns, and you can take actions until your 100 turns are used. So walking a tile might take 80 turns, and running that same tile 40, giving you an extra tile before the other creatures get to go.
What happened here is, a commit changed how limb breaks affect turns, but didn't put a maximum cap. Meaning that players would spend 0 turns moving. If you don't spend any turns, other things in the game never get theirs. In other words, time stops for everyone but you.
