Does anybody else...

I just tried and it's working fine here, at least on the early stages of giveaway creation.

Have you checked that the groups you are in are shown in the sync list? Sometimes it bugs.

No, that's the thing. It says "No Groups found"...

Works for me, i can select groups from the drop-down list.

No idea. Maybe too many groups? 80 :O

Working fine for me.

Hmmm, perhaps there's a problem with your profile privacy

Yea for some reason the resync thing jst removed all my groups lol. Guess have to retry till they pop up again.

I had that issue a couple weeks ago...didn't even realize it immediately so don't know how long it had been going on but my groups were not showing.
Wasn't sure what caused it since I do sync more than once a week usually but it fixed itself after I synced 2-3 times in a row. Haven't had it occur since. Not sure if this will help or not but its my experience with that issue.
