These addons aren't incompatiable but I have a particular issue with PAC3 when I try to hide a weapon from FAS. FAS guns flash in and out repeatedly instead of being hidden (draw weapon = false). Not sure if I should ask the PAC guy about it but it only happens on FAS guns AFAIK. I get no errors in console or anything just the bug itself. To further explain the "flashing" is the gun being hidden and reappearing every other frame.

here is a video demonstrating a user hiding a weapon to give better context.

I've noticed taking screenshots does not show the weapon when it is hidden but when it is shown, but it clearly demonstrates the problem anyway so I will post screenshots.

This is a screenshot of me holding an SMG: https://gtm.steamproxy.vip/ugc/942825260727429274/6FE5F57CD1DE9CF8A8A8AD896BE391A52D0374C0/
