Random question, but what happens when you play with this mod on Peaceful Mode? I would hope the biters are still hostile to each other, while all being friendly/neutral to the player, right? Or would it make them all peaceful to each other as well?

It also makes me wonder how/if it would still function with the Truce mod, which is supposed to start with Peaceful Mode, but then disables it after a certain amount of time.

long time for a reply, and this isn't event a v2.0 compliant mod anymore, but I think even in peaceful mode the biters would still be fighting yes.

The Truce mod likely just does the "Enemy" faction vs the "Player" faction and changes the hostility state. The other biter factions are different "Forces" and so may be missed in the mod programming there.

I don't really plan on upgrading this mod... unless someone is desperate for it

I completely forgot I made this comment lol. But yeah, no worries, it would probably be more complicated to update than it's worth
