I'm having an issue, that might have already been solved, but I thought I'd just post it here.
When I enable the T+T set, only around half of them show up, and some don't shoot anything. I was wondering if there was a conflicting weapon or addon, or something. At first I thought it might have been Zapt, but I remember going to a server with T+T and Zapt at the same time. I disabled all of my weapon add-ons besides the defaults, and the same thing came up. I haven't tried disabling everything yet though, so I'll go try that right now.
Edit: Just tried disabling everything, same thing happened, and yes I did have the default gun enabled.
