I have a bug related (probably) to this plugin.

Namely, the issue is that PVP on PVP zones does not work.
It is known, if I disable TruePVE then it works but on the whole map.
Previously it worked flawlessly, but now I have no idea what is going on.
This is the config with TruePVE:

The problem turned out to be in DynamicPVP, but I have already fixed it!
