Does it stop queuing and just freeze or does it queue but never accept any?
Have you tried using the latest beta at all just to see?
beta will never be older then the release the thread is but the beta never actually is. Give it a try just to see if it helps at all.
I have 5 guys running it right now and none of them have managed to get the issue and im watching them non stop, kinda weird. Maybe a more recent change I did fixed it.
Raphus, Hawker, and I have been spending all week trying to find it and we are really close, the moment we have it fixed we will push it. It is an extreamly hard to find one compared to a lot of the other issues.
