probably crafted something that required an ingredient not in the game yet. i noticed when i crafted certain items that it WOULD indeed craft them. but in a strange way compared to how the other items crafted. luckily i just deleted them without placing them and restarting my game. i believe you are crashing because the game is trying to load something it doesn't.. 1: have the sprites for. 2: notices you are further than you should be and is preventing you from starting. or 3: the game just doesn't get why you have those items and its crashing on confusion lol
