There is a bomb wall in Turtle Rock that when you attempt to blow it up the game crashes. It is the one in the candle snake room.
That is strange in the version I have, you can't even break that wall, in the map editor is just a hitbox wall. The error you show seems like the bomb was not properly initialized and you wanted to use the Explode function
Hmm... Do bomb arrows not fully initialize the bombs in certain cercumstances? That could be it then.
