I think.. not a BUG but #14
Description
First of all.. I'd like to say that this happened because I installed a lot of mods.
The problematic part is that the game doesn't crash when you start it, but when you use the spawn egg on the ground after starting the game.
motion is the same, but the fake player is not summoned.
I'll check it while organizing the mods myself and upload it again later.
I used a translator, and my English is not good, so it may be difficult or impossible to read. I ask for your understanding.
