This Mod is now compatable with my Incubator/Insemination mod. Note compatable, but seperate. Your Earthling can't use the incubator at Dumpsterfire, but at least it won't crash/bug if you try.
Also reviewed files to see if Earthings would appear in the world. Seems like they might, although further testing is needed. Just in case, they have been added as a rare race possibility for several Slave generic NPCs, so if you keep visiting all the slave traders, you should find one. Story-wise, some of these particular Earthlings don't know that the world of Kenshi has given them superpowers: They think they're the same as everybody else.
