If you wanted to make a custom missile and it's done, so you make a hypersonic jet (for example) and equipped up with pylon, your custom missile will be "stretching". So in order to avoid this bug, you should use a fuselage, just change it's shape until it looks like a pylon but have no pylon purpose
Sorry for misinformation there's actually no way for the stretching of missile even tho you use fuselage..... My bad
@TouhouFan11 But that is not a long-term solution. The fuselage cannot abandon weapons, and some other characteristics cannot be completely replaced.
@JSTQ yeah i know the solution instead of using pylon, use fuselage
This is the first time I have heard about this bug.However, similar bugs may indeed occur when the aircraft turns
