Hi, am I am currently using TruePvE on my server, and want to add these Raidable Bases as a buyable reward. Player to Player damage is prevented, but one can still kill murderers and scientists, so NPC damage is fine. TruePVE also prevent base damage though...

...I am reveal my lasiness now. I have not tested for myself. If you don't know, is OK, I test for myself later anyway and see. 

Secondary question : If I set this up to work as I want on my o
LAN test server, can I copy the mod and it's settings straight over to my online, and avoid wading through the settings twice?

This is compatible with TruePVE and does not require additional configuration.

Yes, you can copy to wherever.
