When I click to accpet some ones invite I keep getting the same use all the time something is wrong with this

It's not a bug, it's the backlog of unaccepted dances from last Masquerade. :)

I'm having a strange issue myself. After dancing with someone, I refresh the page to see how much time I have left. Then I notice the user who was under me, has moved above me in place of the original user I danced with. This has happened every single time I have danced with someone ~ :( ~

Thanks all the people who ask me I cannot return because of it

You're welcome. I think it should clear up once you accept everything.
