Hello. I made a simple modded minecraft server for me and my friends.
The problem began when we found End portal. When someone's dies in End / Divine RPG world everything just breaks.
After dying you'll get respawned in Iceka world, not in the normal world. Sometimes after respawning you'll see Iceka world chunks far from you slowly unloading from memory. Console will flood with messages like:
Iceka is a duplicate of another world, remove uid in the world folder to load it"
If you'll somehow manage to your normal world (happens sometimes after death) your bed will not work, Essentials will break too.
When using /sethome a new home point will appear in the config with world name: "world"
But when you'll try to use /home it will say "Error. Invalid world."
