Maybe. If they do its likely a bug especially if they borrowed some of the code from fuling villages. I have this fuling village adjacent to a dragur village on a server I don't own. I have not attacked either village but every 3 days all the mobs respawn (if I am near enough to trigger the respawning) they fight until all the fulings are gone. There is always 1 shaman and 3 fulings in the fuling village and the body piles in the dragur village continually spawn until all the fulings are dead but neither side touches the other's buildings.

I first stumbled on this when I was still in bronze gear (gathering iron) and every once in a while I would go back and watch the war and then sprint through and pick up the goodies. When I built my plains base it was within walking distance.

When I was in Iron gear I raided the barley. When I went back with blackmetal gear one of the barley fields had been replanted.
