ive been aware that this can happen, do you remember what was happening on the game when it happened? still have not gotten around to fixing it bc I'm not sure what's causing it the fight is still winnable like 90% of the time tho, you were probably just very unlucky with this pesky bug.
i remember seeing this happen when a player got completely surrounded by other characters, making the pathfinding algo softlock when trying to figure out how to hit someone, did you think that happened here too?
