well, we were discussing your weapons in admin chat, you had about 5 (i forgot to take a screenshot but other admins saw it), and you had a bomb, multiple guns and knuckle dusters. you then left, came back and had a bomb and knuckle dusters again, that's when i decided to ban you.
i don't often ban players for weapon hacks so i'm not sure if there are any bugs that may cause it to tell us you have weapons on two occasions but i'm pretty sure it's because you spawned them for yourself. the reason i don't think it was a random bug is because you /q'd with a bomb, a couple of guns and knuckle dusters and when you came back, you didn't have the guns anymore but you still had the bomb and knuckle dusters, so i'm guessing you were only half-way through spawning your collection at the time i banned you.
i may be mistaken though if there is a bug with /pweapons that i'm unaware of, if there is then i will give you the benefit of the doubt.
