[BUG] Paper spigot crashes, when world was moved.

[Peda1996]

Paperspigot sometimes try to access data, that has already been unloaded. For this reason paper crashes. One fix Idea would be to delay the world move event. (maybe by about one minute or so?)

Or is there a possibility of loading worlds from a different folder (not the root one.)?

Also a simmilar problem was faced here: https://github.com/PaperMC/Paper/issues/3063

According to https://www.spigotmc.org/threads/loading-world-from-an-external-location.470857/ Also loading from other directories should be possible.
