Hello!
Is it possible that,t if you check in disable Test Flight in the Simulation Start window in VAB it disables Test Flight for your game?
In my new RP-1 career I have played 4 years game time without even a performace loss. I thought there is a bug somewhere with my install. Just for trying unchecked the disable Test Flight in the simulation start window and started a simulation. In the next three real launches my engines failed. Even though they had around 6000 data and never failed before. It seems to me somehow Test Flight was disabled until I uncheked that option in the simulator.
Do you think I was just luky or could it be a sign of a bug?
