An important bug. If your maturity reaches low enough you need help to change your diapers, but if you recover maturity, you still need help. So if you didn't unlock the ABDL club before that, you can't join as you need to put on undies for the last test

I wish this "lock" didn't exist or had a toggle.
From full maturity I once put on a diaper, had an "accident", changed into another one, had another "accident" and suddenly I could no longer change my own diaper.
I get what it's going for, but honestly it's kind of frustrating that it's punishing you for engaging with a mechanic of the game because you can't choose what diaper to change into afterwards, which isn't really fun when there are so many different brands in the game. And from what I'm aware of there aren't actually a lot of places to get someone to change you to begin with.
That's what I mean, there's not a lot of them, so if you have an accident, intentional or otherwise, you got to cover a lot of ground just to get changed. And afaik you don't get a say in what you get changed into, so once you reach this "lock" it is rendering the wide variety of prints you can find null.
I just want to clarify that this isn't tied to maturity : you can always change your own diapers. Instead, it's an area lock that prevent changing in some areas. What can occur,though, is a bug that incorrectly clear the "allowed to change" flag when you exit. In that case, a simple fix should be to go to your home, save and quit, then reload. This should clear any incorrect flag and allow you to change again.
