Within the first week, right after I built my first turret, a group of 3 (I play on Phoebe) friendlies pops up. I decide to test out the new turret on one named Johs. He gets incapacitated, the rest of them get pissed off, and a fight ensues. Next thing I know, I see a 'headshot' on my lee user. He fights until the end. We get him fixed up, but both of his eyes are gone now, I wind up recruiting Johs.
Since then, lee wielder (can't remember his name offhand) has given me a world of trouble. A male psychic drone passed over and caused him to go insane, so I had to arrest him. He was my ONLY researcher at the time. Recruited him again, and I regularly get warnings of a mental break because the little boomer just doesn't want to eat. He consistently starves himself every time he goes to that research table. Think it might be because he can't read anything, but whatever. I have to draft/undraft him every time he decides to go on hunger strike, which is every couple of days.
And, to top it all off, he complains when it's dark. How can you even TELL that it's dark?! You don't have any eyes!
