Currently the only problem I have in this game consistently is the Psychic Drones, especially if it hits early enough to not get a few rose gardens up.
At the moment when a colonist cracks it's exactly the same as the colonist going nuts from colony issues. I propose that when they crack from a Psychic Drone it only lasts as long as the Psychic Drone is active (perhaps make the gender/affected crack sooner and the drones last longer for balance).
This leads me to my next suggestion. I recently had a game where very early a Psychic Drone hit and my female colonist 'broke' and began wandering off. My only option was to arrest her and stick her in a cell. When the Psychic Drone stopped I did the usual of trying to get her back into he colony. This got me thinking, when the drone stopped she was in perfect mental health again and it seems odd that I had to convince her to join the colony. Why wouldn't she to just rejoin automatically?
I thought about an option to restrain people who are nearing a mental break (or anyone I guess if you're into that

) When I mean retrain I mean literally tie them to a bed. This way if they come back to their senses a doctor can release them and they automatically rejoin the colony. If, however, they go completely psychotic you may not be able to restore their sanity and their screams could unnerve the other colonists nearby. After a period of time you may decide it's better to put a bullet in their head.
At this moment in time the most unsatisfying way for me to lose a colonist is due to a Psychic Drone as their is very little I can do to stop it happening. (Personally I think a small drone should appear somewhere on the map which you can destroy but that's another topic...)
Anyone have any other ideas?
Thanks for reading.
