Thanks for the quick reply, I just tried, switching back to main mission and then reverting to launch works, contracts are not deleted! Only one test though
I know I am quoting an old post but unfortunately I am having exactly the same problem in KSP 14.5.2243 with the latest version of the mod.
Anyone having the same issue or a fix?
Will investigate further, will check whether returning to the main mission and then reverting to launch does not give the same problems..
