Can you provide the logs? A list of mods would be helpful, too. What were you doing when this problem occurred? What version of the game are you playing?
I just checked—it's not crashing. Either there's something wrong with your game, there's a mod conflict, or a completely different mod is crashing, and mine is just a side effect. Unfortunately, based solely on the statement “the game is crashing,” I won't be able to help you at all.
okay, so, i enabled this mod back, ran around and generated new chunks, and nothing - i swear i have not removed any other mod, only added new ones. For now lets say that it fixed itself up, and if it happens again, i will be ready
