Heh, nice to know the preservation guys give you a little break to start with.
Anyway, yeah, I have enough trouble dealing with the endless AI assaults without random jerks coming in and blowing (irreplaceable) stuff up in my rear echelon. I did mean "Mining Golem" instead of "Devourer Golem" though. I love the Devourer, he's my (very abusive) best friend and keeps the AI ranks nice and thin. The mining golems are just annoying. And yes, the pattern is "if it helps me against the AI even occasionally, it stays".
