When i logged in on my character, flies started buzzing around me, sounding really loud. And when i opened my inventory i could see that the skin of the character looked like a corpse and the flies where visable around me both with my inventory opened and closed.

When i run around the buzzing stops, but my character still looks like a corpse. And when i stand still for just a few seconds, the flies reappear.

I have tried to both exit the server and game, but the bug wont go away.

Honestly i can't play like this, because i can barely hear anything except the flies and i'm afraid other players might hear the buzzing too.
Please help me.
