in this project, it is supposed to add 1 item to each of the lists every time there is a new user (when the user id is more than the list length).

but there are some weird things going on.

1. the username list is 5 items bigger

2. the username list has 2 of the same name in a row, several times. for example, ImagineIt is listed twice in quick succession. this makes me think that hwen an item is added to cloud data, it is inadvertently being added twice.

so either tell me what's wrong with my programming, or these are some bugs

Yeah, I have similar problem with my Tower Defense leader board.

The cloud variable to hold scores has like 59 entries and the names list has like 47 entries. I can't quite figure it out.

That's similar to what is wrong with my chatroom. The cloud data list won't go longer than 16 items. If any more are added, it deletes the last item till it's 16 items. If I delete any of the cloud data, the list is restored. For some reason that only happens when the project is shared. I unshared it and it worked fine. Weird.
