Running my old 44.10 fort in 44.11, not much happening, more were-tortoise experiments have set me against doing anything with them other than swift executions, they keep biting people in the lower body because they are very short, which they then shake into a broken spine. The people who get bit in the arms keep turning, with the now-crawling people do not. I'm done with 'em.
A few quick reviews on "and mulling over the recurring memory changed", the worst memories stop being remembered and are replaced with a tendency to more easy get new bad ones for smaller problems in future, angering quickly or being very prone to stress or similar traits. The less bad ones are replaced with, well, not caring about that problem any more for the most part. Avoid really bad thoughts as it's all a bit PTSD, but don't sweat the small stuff because they mostly adapt to it. Willpower rules, trained military have way less problems.
Still gotta treat them pretty well, and care for (or kick out) the ones that are freaking out. Sadly, my most angry dorfs are all married to multiply legend skilled dorfs, so they will stay and suffer like good little spouses. Must turn off hauling trade goods for upset dorfs though, starting a fistfight at the trade depot is bad for trade.
