After starting the Server it closes by itself.
It was an snapshot-only Server so i played on the versions before too. Until 15w51b everything worked fine, but with the Update 16w02a the Server crashes.
I detected, that the regionfile -1;0 is corrupted an makes the Server crash instantly. Before the world worked fine without any problems.

I also copied the file to my normal Minecraft and tried to start the world with different versions. Before it worked, but after the uptade to 16w02a minecraft crashes every single try ONLY AT THIS WORLD.

The issue seems to be an : "Exeption while updating Neighbours". It looks like it`s an error made by an "DLDetector" and a "Beacon" inside this region.
I also tried to fix the corruptet file by myself, but i couldn`t match the issue inside the file.

I hope u can fix it like before (same error, just with water&lava, air and redstone) and enable a tool to "Chunkfix World" in homescreen.
