Apparently I'm supposed to ask this here. 'Technical issue'
I reported this in the bug section and it got dismissed as a 'technical issue'. Which I'm 99% sure is a load of nonsense because this doesn't happen when I play custom games with bots and my internet connection is fine. I checked out the similar thread on people getting disconnected and my issue is similar to that but not identical.
I checked firewalls, I went through all the hoops and fixes and nothing. Then on my thread I get a buck passing answer that 'its a technical issue and I should ask it here'. Weird how I'm getting a technical issue when the event starts and haven't had one for the whole year I've played this. I can't even risk 'testing' if things work too many times because the penalty gets longer and longer.
I'm not expecting anybody here to help because I'm fairly certain this problem is server related as there are others having similar problems with this, even on console but I'm doing as I'm asked. Maybe there are things I haven't tried.
I guess I'm a little more 'impatient' and frustrated because this is the anniversary event and time is wasting when I can't play the game and I'm possibly causing others inconvenience when I'm... doing whatever this is.
