Return of Reckoning

Okay, i know bug reports go on bug tracker, but this is a really nasty bug, i want to know if anyone has heard of this before or knows what to do. I was doing a sc premade with a few people, and i decided to logoff and get on my marauder. I relogged and now everytime i accept a group invite, or invite someone to group i instantly crash to desktop. Even after i switched toons back to my DoK its still crashing me as soon as i join group or invite someone. This really sucks! Any ideas?

I've tried it. Fixed it by everyone relogging and reforming party

happens sometimes, yes.

and yes all groupmembers need to restart the game and it works again.
