Maybe that's why the forts fall apart more rapidly. The other day, I was testing out a new fort design and because I was trying to get things done ASAP, I didn't bother with Therapist and just handled stuff manually. Not particularly difficult with only the original seven, but I didn't bother checking any of the immigrants and just let them haul stuff around. Didn't get a dining room set up either, because I was building a big centralized 17x17 room that had been channeled out from the surface down 7 z-levels and then roofed over for some cave adaptation prevention.
Anyway, while I was digging it out I goofed up and a miner got killed in a cave-in. Unfortunately, a young female immigrant who was starting to get friendly with him took it rather poorly. She was very upset, and the expedition leader failed to console her. She threw a tantrum and punched him in the brain. She got her ass hauled off to a quick and dirty jail I set up for her. But it sparked a mild tantrum spiral which got another dorf killed and crippled my mason who was responsible for engineering a good chunk of the project (it seems you can't get a good tantrum spiral going with only 15 dorfs who've only been around a few months). Since I was being impatient about this whole thing I just abandoned and reclaimed, because I didn't feel like waiting for the mason to heal, and the expedition leader with the caved in skull was the one that was the initial doctor.
