Something I am very curious because I recently had an encounter with insectoids and by just luring them away from the hive for some reason they just stop seeking out colonists and proceeded to try getting close to the hive yet again, was actually able to tame one without destroying the hive and getting constantly beaten to death so i'm curious what really caused this. I will mention since it is important I do play with mods, so there is a possibility one of the mods affected the behavior, but I don't think it should. Infestation was provoked from a quest and spawned in a room, where I proceeded to lure out one of the insects and closed the door on them. Oddly enough if the insect was attacked atleast once it was actually aggressive for some time when it was away from the hive.
