Just had a save file corrupting crash when trying to launch a sounding rocket (Umbra Space Industries) from Central lakes via Kerbal Construction Time. During a previous session I had used this site for a successful launch. This time, however, in addition to having Central Lakes selected as the launch site in the VAB I also had used the Kerbal Construction Time pop-up menu to designate this launch site. A copy of the log file is saved and available.
