We do occasionally run 1.1.1.1 for some of the older missions that are great but not yet stable with the 1.2 platform... So make sure you leave your 1.1.1.1 install alone as it may get some use.
Basically at this time anything with tankers / predators / jtac / AWACs is "broken" while tankers seems to be the main cause of many connection issues. The others simply don't work the way they're supposed to without what quite often becomes substantive editing (for someone like me who is very weak with the editor.)
Even when you fix the problem for some people, you create problems for others. The act / react process gets so frustrating that many throw their hands up... I'm basically at that point right now and would rather run some more intricate missions with 1.1.1.1 where they work fine than have to spend hours shaving off parts of those missions that don't work.
It's an absolutely great group of guys who are friendly, patient and understanding. Please make sure when able that you join TS3 (SimHQ's) so that we can talk you through any of your troubles should you have any.
Speaking of 1.1.1.1- Blooze recently commented on how much he enjoyed the "Separatist Aggresssion" campaign... it's a lot like our "op bactria" and takes a few extra steps to add an immersive environment what with actual "live" audio communications with JTAC and expansive triggers. Wouldn't mind letting that one run here over the weekend. So make sure your 1.1.1.1s are all polished off and ready for deployment.
