Anyone Else See This?

[Justificus]

After today's patch (5/20) I loaded up the 1.5 Beta and started one of my missions I made with the previous version that has several of my modules and lets me fly around in a sandbox sort of area to do things in as I learn the ME. Well I try to fly my Mirage. When I hit fly I'm in the 3rd person external view of a different plane... Go into the editor and check the plane's settings, all look good and I try to fly it again with the same result. So I go back into the ME and delete it and put it back in at the same airfield. Same result. I try adding a 2nd one to another airfield and have the same result. I try another plane, the F-15, no problems, try the F-86 and have the same problem! I then try the A-10, no problem. The Gazelle, no problem, the Huey, no problem. Those were the only planes I had in the mission for the blue side. Adding them into the mission again wouldn't work. I found the I could fly the included missions with those modules but not in that mission I made. I tried creating a new mission with nothing in it and the mirage appeared and flew just fine...:huh: Only n the mission I created those two planes, and maybe more that I haven't tried yet, won't appear as flyable in my mission no matter what I do. Are others seeing this with their own missions? If so, anyone find a work around besides starting all over again from scratch just to get those planes included? Hadn't experienced this before in all the years of playing this games various versions. Thanks for any insight.
