I'm not sure how this happened, but it was an interesting bug. I kept trying to switch to my weapon but it wouldn't let me. So I thought I'd just waste all my grenades and see what happens, but they would just keep refilling! I had some fun with that for a while, since they didn't explode, but finally i screwed it up when I right-clicked instead and a grenade detonated. I made the video quickly, so it's a lot of the same for the first 1:30 or so, so you can just skip to the end to see where it gets fixed.
(Note: Going to bed now so I had to post before the video finishes processing. It should be up pretty soon.)
