I tried using the hide parts feature (on ios) to get some parts out of the way, and when I went to make them show up again, I noticed that some of them were deleted and would not show up after multiple attempts. Some were also in different positions. Why did it break my fuselage?
@ReinMcDeer That's most likely what caused it, not all parts were connected.
@ElevatorEnthusiast747 double check your connections
Resizing fuselages shifts the whole plane and non-connected parts won't move with it
Disregard the part about the parts getting deleted, none were deleted, only changed position.
