2nd Question.
When i start the server at the first time, server start to create the world. Does the server create skyblock map or the usual one?

I can't do anything with the log, it doesn't allow any conclusions about an error. If the problem persists, please send me both the client and server logs

the server zip file should contain a preconfigured server.properties. The Level Type has to be set to "tatters"
level-type=tatters
