We do fly coop missions mainly in WAW but have on occasion have flown some Jet Age missions. I understand one of our members is presently working on a coop Korean War and a Viet Nam campaign as well. Our online play is coop and we like to fly campaigns of two categories the first is player made non dynamic and the second is player made dynamic campaigns.
As for the JSGME we have found in the past that they can cause game compatibility issues. Our solution to this is to insure everyone has the same mods activated in the same order, as order can also cause issues. Honestly we seldom use them but a player is free to use any mode that does not cause a compatibility issue.
Aircraft type and model issues are usually the commonly known ones that have stemmed from aircraft being adopted into BAT before they were fully developed or tested. Thus the need to switch to different aircraft.
One thing we have become aware that did not seem to be such an issue before is the need to be more controlling of AI performance in online missions.
Mission testing is much more important now as one can not rely on everything going exactly as one wanted. This is both good and bad but if on want an Ai to attack a target one does expect it to do so and this can take so doing to get it to do so.
Also we have become aware that different maps or versions of maps can cause difficulties. We have developed certain mission building protocols to overcome these issues as they become known. One such issue is unexpected bumpy airfields . In this case a map builder seems to have forgot to smooth out an airfield. In solo offline play these are usually not even noticed but can unexpectedly appear when used online and lead to restart nightmares. This is due to the change in the number and skill level of players involved. The answer we came up with was to simply overlay any airfields without runways, with a Test Runway 4,5, or 6. the larger red airfields, found in the Stationary Ship listing. Doing so usually solves the problem but these too have some interesting traits one need to be aware of before using them.
As this seems to be turning into a book it might be best, If you wish more info on our online play discoveries or even to join in on our line game, that you
