If you join an server 2 time, It crashes
Step to reproduce:
1. Go to Muitiplayer
2. Join an Server 2 time
3. Your Minecraft is crashed
Why it crashes? This is because if you join 1 time, Server send required information to constuct BlockEntity. If join another time, Then the server forgot to send required information to constuct BlockEntity. Then it automatically quit and crashes. It also automatically HideGui before it crashes.
