I have an idea, this might solve the current problem

I have an idea. The accessories purchased in the store are directly in the backpack instead of directly on the weapon. This may solve the current problem, but I don't know how to make the corresponding modification.

I'n not a repo admin, but still:

First of all, here you can find a guide on how to contribute: https://github.com/firstcontributions/first-contributions
Furthermore, the code you posted is not really helpful. There's a lot of stuff going on that is not in the framework (looks like some kind of skill tree thing and limited stock scripts). If you have a sugestion, please describe as good as possible what your idea is and if you already have a working code sample, at least extract only the relevant part
