I have installed Gredwich base and made sure that I have every dependency but nothing from Gredwich tank pack shows up in the menu at all. It's like I haven't even installed it but I definitely installed everything. Can this perhaps be a conflict with another vehicle pack?

I also noticed that there are no .gma files to do with this pack in /garrysmod/garrysmod/addons either, as I said it's as if I didn't even install it but I have uninstalled and reinstalled it once already and it still didn't show up. I might have to try uninstalling everything and just installing this pack first. Any ideas why this is happening?
