I did not notice the issue unitl the last update this past Friday (the 13th- hmmm ).
Something is corrupting the mission files when you save them. I have looked over each .log file I can find and do not find anything regarding the ME. But, I also have noticed if you take player and client aircraft and change them to AI then watch the mission the Triggers will work for the AI but not from player or clients.
As player or client I can fly the mission but none of the triggers work.
Another strange issue I found Sunday night was I built a mission then uploaded it to a dedicated server , mission did not work. But when I took the same mission and hosted it from my PC (mission was built on my PC) it worked one time then next time I tried to get in the mission it would not let me get into any aircraft pit. However I was able to watch as though I was watching a track of me flying. AI had my call sign.
Anyone try rolling back one patch and build a mission and see if it works yet? Was thinking if we could do that and copy the mission to desktop, then update and build the same mission in the ME again until it has the issues. We could then use winmerge and see what might be different.
Just a thought, I can try it but wont be able too until this weekend.
