Doesn't work

The Tool doesn't work because WorldGuard uses incorrect UUID's in the regions.yml, so the Tool says that there isn't a name with these UUID's. How can I fix this? We want to downgrade because WorldGuard 6.0 is very instable. I already tried to write an own programm, but that doesn't work too because of the UUID's. Maybe I can see which Fake UUID belongs to the right UUID.
Thank you for your great work!

Start by reproducing the downgrade with the affected WorldGuard regions.yml and inspect how the tool resolves the UUIDs to region names. Compare the UUIDs in the input and output files; done means the converted regions.yml uses mappings that WorldGuard 5 can resolve without missing-name errors.
