KSP Version: Version 0.90.0 Beta Problem: When flying a specific rocket build, at about 6000-7000 meters, it will spontaneously combust (and by that I just mean explode). The top stages are still perfectly intact, but useless as I am assuming I have enough fuel in the first stage to get into space. The output log simply says "structural failure" between parts, but these are parts that have no reason to fail. The ship has a slight tilt that will flip it if not using ASAS, but I don't think this has anything to do with the bug.
