You got an ETA on this issue? If there is no ETA available, is this issue considered 'high priority'?
I'm sure you are aware of this, but this issue appears to happen when there are parties of 2+ players. When I am playing solo, there are no issues. When I play with a group however, wait times often exceed 15 minutes. I'm fairly confident the code you guys are running requires a party match of similar size when creating a game leading to long load times.
