1) Ah, right, thanks!
2) exp but not mind, right? I have lots working who are crying with low mind, especially those who get easily lonely.
mind should automatically be regenerating. if it's not, you've got someone with the "scary" trait wandering around lowering everyone's mind. or you're in a "stuck pregnancy and people on the overworld" bug.
now, these days there's actually some reason to want characters to have low mind. there's a whole "cry" line of attacks that require ythe user to be crying.
if that's not something you want, get rid of all "scary" servants, and just use mind potions. they're cheap and pop up in the store often enough, and are also craftible i believe, but buying is by far the preferred option.
