A consistent new bug that only appeared after the December CDK patch. If you move your camera above about 25km the mission creator program crashes giving this report.
Its easy to avoid doing this however it can be done on accident and like me I accidentally saved the project. Doing this made my camera by default start at the last altitude which was the height the program crashed. Essentially I had to redownload CDK because I dont know how to reset the project outside CDK.
