Hello,
I was recreating a historical aircraft in ksp 2, when I realized that at a certain time after launch, due to a certain maneuver or because of behavior of parts, on of the prior listed reasons (I am not sure which one is the true cause) the game enters a freeze state where it becomes unplayable. There are 3 levels to this, the game either just deletes the craft but lets you revert to VAB, the game deletes the craft and freezes, forcing you to alt f4 or the game crashes entirely. I have attached an image of the game in the "game deletes the craft and freezes" type, however it seems I cannot add my Ksp2.log file.
