My game has crashed several times in a game but due to a messed up entity. Now whenever I try to create a new world, it keeps happening with the same error except it has to do with the initialization of the level. Can someone please help. I am trying to play modded minecraft with my sister and we had to try to restart (create a new world) because of this issue and now I can't even make a new world in forge. Here is a pastebin link to my crash report. Pastebin: https://pastebin.com/7RNMjnvZ
