1.9.5. auto-declining bug on invite

Hi!

What do I do when I can't invite anyone from my wait list because they all appeared as auto-declining my invitation at the same moment as I invite them. they also gets removed from the list. After that, I was tried to invite them from the friend list (social panel) as they're there for some more seconds. Same result.

Edit: I also turned off all other addons and also deleted the oqueue variables from the WTF, installing a fresh oQ 1.9.5, still the same result.
