Hi, thank you for bringing this to our attention, after some thinking the following things have been updated/changed.
The Entity-Damage claimflag will not be left up to the playerbase, it opens the door for exploits and severe griefing.
Enter-Claim claimflag will remain true globally, turning this off defeats the purpose of RLCraft.
Some claimflags should be left up to the playerbase, if you want to reply below and suggest some, I will pitch them to the team and consider them.
I do agree that the villager griefing is getting out of hand, and that something needs to be done about it, I will look into expanding our death logging plugin to also overlook mob types.
For now, please keep your villagers, and any mob of value Away from places that a playerbase could access, behind solid blocks, not doors.
On another note, if this issue pops up again, please post a claim rollback, as we can get them back that way
