What happened?

I can't even generate a world, and I can't see what the problem might be other than on the crash screen it says:

So I have no idea how it could be reproduced.

This is also the 3rd time it happened to me.

Version

1.0.0

Provide the log

crash-2022-03-12_20.19.52-server.txt
crash-2022-03-12_20.25.59-server.txt
crash-2022-03-14_03.47.18-server.txt

Seems to be a problem with Terrablender.

Thanks
At least I know it wasn't me, lol

Is caused by TinySkeletons. Will be fixed in 1.0.2.
