HAHAHA even minecraft blames you now henry

Please remove vanllia fix. What it does is really bad for your game. This bug does appear to be unrelated to that, but regardless please remove vanilla fix.

I don't really see an issue with Vanilla fix it's been good so far

If the game is crashing there is a reason for it. Stopping the crash is like disabling the air bags in your car. Sure that means you won't get hit in the face by an air bag, but there are far worse consequences that the air bags were preventing.
