This bug has driven me nuts since I started in SG, and I was hoping in 1.1 it'd be fixed... but this bug involves molotovs, and as far as I know I'm one of the few people who habitually uses molotovs, so it probably slipped under the radar. But whatever.
Basically with this bug, when you have dynamite out and you have molotovs set as your last used weapon, if you hit the button to light the molotov before the weapon switching animation finishes playing, it has to stop and do the dynamite-lighting animation, and THEN it switches to the molotov. Very annoying thing. That good second or so delay has gotten me killed more times than I care to admit. I would love to see it fixed, and it would probably create a good 12% more dangerous Nixito! Isn't that what everybody wants?!
But seriously. Fix it.
If you care to see an in-game demo of it, I put it here...

Sorry that I don't have fraps or anything like that, but hopefully that'll give you a general idea of what it looks like, and how annoying it is.
