Hey, so i have started up a server, everything is updated, but for some reason when i get hurt or damaged my Minecraft crashes. This has never happened before and i have no idea what is going on. I can play on the server when i dont get damaged, but when i do i just crash. I have included a crash-report on pastebin. http://pastebin.com/ay0nxkgn If anyone knows how to fix this problem please leave a comment below.
