Found many Mystery bugs :D

[Lapayo]

Today I started a little Minecraft round with some dev friends.

We encountered many bugs and also many server crashes. (But I had no debugger running)

Bugs found:

I additionally posted them here, because for me the forum is easier to ask questions etc. And maybe there need to be some discussion.
Also some bugs are very critical and need some publishing

I will also look into it tomorrow, but now it´s time to go to bed (1:30AM here)
