Unfortunately I'm having the same issue, but I can't take it off even in my own house. It just says that I need someone else to help me, no matter where I try it at. It unfortunately makes the ABDL club impossible for me to even get into, because I can't take the diaper off to do that step.
Oh! So, I don't know why this didn't work the first time I tried it, but the issue fixed itself when I closed and reopened the game. It only worked the second time i did that though, as it didn't work before.
