I honestly do not know what caused this crash. But maybe the output can help you? The version of Cuberite is a few days old build.

It was a deadlock (says so above the crash), it could be any of the known deadlocks, or a new one.

We have 3 fresh auth related github issues. All of them are about crashes on login. (By me, @Jammet, and @gargaj).

That seems to have done the job. However, just now, a new segfault presents itself when I tried changing the gamemode for a player.

There's not much we can do about a deadlock unless we have a core dump etc. - we need to see what threads were actually blocking one another.
