Also, regarding the other mod, yeah, I saw it. I'm currently working on the endgame of the Proliferation mod, to finally release v1.0.0. My replicators should be hostile to everything, including other replicator mods. While making my replicators deliberately target other replicators would be interesting, this would mean I add a dependency to the other mod, which I do not want. But I can, however, give them another attack target: the closest enemy force, which can mean player, biters or anything else, including the other replicators. As for compatibility, I don't see why both mods would not be compatible, I made mine as independent as possible from any other mods, so there shouldn't be any issues.
When I'm done with v1, I'll have a look at this and the other suggestions we discussed previously.
