alright i have all the game pacs selected and loaded, ive reverified my local caches twice with no files missing and im still having a problem.

some of the weapons will not recognize their proper mods when i go to the mod window. the 12.7mm SMG gra wont even recognize that i have the 12.7mm SMG stacked magazine or 12.7mm SMG suppressor in my inventory.
this doesn't seem to be restricted to GRA guns only because my anti-material rifle also fails to recognize that i have the Anti-mat. rifle CF parts and the Anti-mat. rifle custom bolt in my inventory too.
however this problem is not universal, the hunting shotgun mods registered and applied fine, as did the chainsaw GRA carbide teeth mod.

this is becoming very frustrating does anyone else have this issue and/or any fixes for it?
other then that GRA vendors thus far have the expansion items available, they are purchasable and no further issues related to GRA. just some guns refuse to recognize appropriate mods.
