Stuck in nonexistent party

I'm currently stuck in a state where I cannot invite folks to parties.

Any time I try to invite someone to party the game complains "The party does not exist."

My party screen shows I have a pending invite to a guy named DpsWins that I traded with earlier.

Any time I try to cancel the invite or leave the party the game says "The party does not exist."

Switching characters, closing game, joining other parties, I still have a pending invite to him. Even on other characters in the same league. Standard seems unaffected.

Please help!

Seems ok now. Not sure what fixed it.
