I suspect that it's the same bug. The original poster on that thread reverted to the last stable,version and it worked for them. I did the same thing and it also worked for me. I looked at the change logs and realized tha there was 2 beta releases and god knows how many internal releases between the builds. That's a large amount of changes to dig through. The old test engineer in me wanted to tighten up the bug report so I stepped through the intervening versions to identify the break point and reduce the work required to find the problem. Since the initial report I have done some additional testing. I created a copy of the mission and verified that it had the same issues. I made the listed changes and then reverted the mission back to the original configuration between steps. Here are the results:
Deleted all AI aircraft - no change.
Deleted all red ground units - normal operation
Deleted all red tanks - no change
Deleted all red APCs - no change
Deleted all red infantry - no change
Deleted all red trucks - no change
Deleted all SAMs - no change.
Converted all red units to tanks - no change
Converted all red units to APCs - no change
Converted all units to trucks - no change.
Cut the number of red ground vehicles is half - noticeable improvement.
Converted all red units to their static versions - noticeable improvement.
Conclusions:
Something in the last updated raised the general overhead on ground vehicles. I was unable to tie the problem to a specific type of vehicle. My gut feel is that the issue is related to the ROE scripting and or the dispersion under fire scripting but I ran out of time to test this theory.
