Sorry for double post but this is extremely important. Have you created multiple weapons with the package script in it? Here's my scenario:
I have two weapons with said package, #1 is working but #2 doesn't. The thing is #1 worked before I put #2 into my addons. #2 works, but the sights to #1 no longer work.
I have EVERYTHING correct, I'm just wondering if your script is loving everything up.
