What i did / Steps to reproduce

I made Paper 1.19.4 server with (now) latest BlueMap-3.13-spigot.jar.. I configured core.conf and thats all

Expected result

I expected world_nether and world_the_end being recognizable by BlueMap

Actual result

Context

BlueMap Version:
BlueMap-3.13-spigot.jar

You have \\ in your config instead of / ... you probably copied the configs from a windows test-setup to linux ^^
Change it to world: "world_nether/DIM-1" and it will work.
Make sure to check all the other config files too, if they have backslashes (windows) instead of forwardslashes (linux).
