A new bug fresh out of the oven!
Currently this behaviour was observed with Marcy Pop at Workshop and would affect 1$ passcode owners. Her option for changing between states is "Get Naked" in both cases, regardless of current appearance. It does switch them as intended, but might be a bit confusing for players. I'll update this post if I observe this behaviour being tied to either Marcy Pop or Workshop specifically, but otherwise NPCs in other stations seem to be unaffected and their dialogue option for clothes change is as intended.
Update: ??? happened to be next Workshop NPC and her options work as intended, so the issue is likely with Marcy Pop. She didn't "pop" in any other buildings for me today though, so I can't verify if her chat option remains broken in other buildings.
Update 2: Marcy Pop has her options displayed correctly in Bank/Exchange station, so at this point I assume that the issue is specifically Marcy specifically at Workshop.
