Hello everybody!
I have a very strange bug that happens rarely on Windows, but it crashes the game.
The Player.log is very obscure, but there is definitely something going on.
Does someone have an idea of what could be happening ?
The error seems to happens where there is a lot of Entity doing Entity stuff, but it’s not that easy to reproduce.
Thank you very much 
Crash!!!
