Server crashes on player joining the_end.

What you expected to happen:

The server does not crash on player joining the_end.

2. Server closed.
3. Server spits out crash-2018-10-06-server.txt involving a pokecube nullpointer.

Affected Versions:

• Pokecube AIO: 1.6.16 (5.19.7 in game)

That looks like sponge is doing something odd, it is somehow allowing a getHome call to occur before the mob has joined world
