So I had *carefully* released my vampire to get some clothes, and after a while she was "done," so I put her back into containment. Then, even though she had a sandal (she only claimed one...), she kept ranting about being embarrassed about not wearing shoes. I then proceeded to dump shoes (and other clothing) on top of her to keep her happy, but no, she decides to claim some shoes/socks, but not use said shoes/socks, and continues to rant about not having shoes even though she has some claimed shoes on the same tile as her (they aren't forbidden or anything and are in her burrow, so she could just pick them up and put them on). In fact, when she was tantruming, she picked up a shoe and threw it while she was wining about not having shoes!
Also, my other vampire had been updating the stockpile records (turns out, that postpones nakedness thoughts), so I dumped clothes on him. He claimed some, and put them on after he was done bookkeeping, and had a full outfit on (I checked). But then he too started ranting about not having shoes on even though he is wearing shoes and has another pair claimed that's right next to him!
So my 2 vampires (one not important that has a motor nerve injury, the other my eternal bookkeeper) are both very unhappy/melancholy, tantruming and have yet to go berserk, wining about having no sock even though they can VERY EASILY get them, or are even WEARING socks. What gives?
