I updated to 0.9.1.1 recently with image pack 0.9.1 (from some 0.8-ish version), and now pretty much all the descriptions of the school clothing are kinda wrong. Apparently, the skimpy, sexy pieces fully conform to school regulations, while all the sluttiest pieces merely "slightly breach" the regulations. Literally everything else is considered very conservative. I'm guessing this is a bug? I usually exchange some of the images, but I only touch stuff in /pc/body, so that can't be the issue.
Edit: I also tried joining the Discord, but alas... "Whoopsie! Unable to accept invite" Thank you Discord for not being helpful.
