I zapped last night before I went to bed, so this morning when I woke up I should have had a different skin. So, I zapped again this morning and it still hasn't changed.

It finally did change just now, but it had not changed last night after I zapped. I am hoping that the bug doesn't happen again. I zapped 10 hours ago last night until this morning. I am using Chrome.

I still don't understand why it didn't change within a 10 hour time period.

Is it possible to zap the same skin twice in a row? I swear that happened to me last night too. I was a blue skin (I think its called navi from avatar or something???) and I zapped and I was still still that skin until this morning when I zapped again.

That is very possible. I do keep getting the same ones over and over again. :(
