Problem: realm crashes as soon as someone leaves the nether. 

How to reproduce:

Step 1, build a nether portal in an existing realm of decent age near a bunch of farms.

Step 2, go into the nether. 

Step 3, go out of the nether.

What did i expect:

To be put into the overworld at the connected nether portal. 

What happened:

The realm did a rollback, after it said it disconnected When I got kicked out. 

How to fix:

Remove all possible farms and redstone works and if possible villages in the area, basicly making it barren and useless if you want to use the nether for faster traveling.
