I, too, am having this exact Problem. I will try to replicate and upload the .mis File Here.
I was able to fly low level directly over where they used to fly; they are at least for sure no longer flying there (I had seen them there before, so this is definitely different). I believe something changed in the recent updates. If I recall, the AI has significantly changed. I intend to fly directly over the Airfield where they are supposed to launch from and see if they have even moved or if the engines are turning on. ( Just got the 28 Oct Hotfix) So it will be slightly different, but they made no mention of AI Changes. TBH, I am hoping the 28 Oct Hotfix resolves it. Will check back here in a bit.
