'Found 0 region files'

[HStep20]

I've got an MC world that I pre-rendered with Chunky. After some lag issues, I cut it down with MCA Selector, and replaced the old world with the new 'culled world'. Before, I was running Bluemap, but switched over after deleting chunks.

For some reason, Pl3xMap is not finding any of the region files within the world, to make a map out of. The world plays fine, and I can see the region and world files inside the 'world' folder, but this is not recognizing them. It rendered the nether and end perfectly fine - Just not the overworld. I've only changed IPs and Ports for the web server to match to my old Bluemap site

This sounds weird and im too lazy to reproduce these steps.

could you upload the log - are there any errors or warnings?
Are you sure you did not disable the map for overworld?
How large is your world? could you upload it, or at least s part of it, so i can somehow reproduce. Im Kind of lazy try to figure out how to trim a world with thirdparty software i have never heard of
