World manager renames worlds

Hi, here I am again with a world related trouble with spongevanilla-1.11.2-6.1.0-BETA-17

This is more a quick fix than a bug reports, I don’t find any other related topic and I don’t have this issue on my local windows server, only on my distant debian one.

I tried with nucleus and pjw world commands.

Basically, I had a basic world royalnew with associated nether and end. Then I imported a new world Artistkorea. The world list shows everything as it should but when I try to load Artistkorea then my main world is also renamed to Artistkorea.

The main trouble is that I cannot unload anything either teleporting to the other world because they have the same name. A reboot temporarily fixes the problem but it occurs again.

Quick fix for this : When importing the world, one should rename it asap then teleport and finally rebooting server.

Any more information or suggestion with this savage rename is greatly appreciated.
