Hi there, i’m running into some issues making some custom weapons. I have 0 mass small detatchers and parts saved for use. And yeah I’ve built the missile fuselage off of the dead part of the detatcher which then goes on a pylon.

So it’s using an interceptor missile, and when fired it doesnt launch off, I had to try detatch it off the pylon after firing it. I brought my test missile onto a plane through sub assembly, and noticed that the small detatcher got duplicated 3 times in the same spot. Any ideas what’s messing up here?
