1. You can't detonate stickies if you switch weapons.
2. Some spy disguises don't go away, even when they're firing a weapon.
3. Ubercharges are uber-weird.
4. For one glorious round, i was an engie with a wrench. Still my Lvl 1 sentry was killing EVERYTHING.
5. Sapper didn't work a lot of the time, seems like a novelty item. I know it CAN work, b/c all my stuff has been sapped....
6. Scout with Sasha = WIN
7. had a pistol that shot flares ... with 200 flares in reserve
8. Was an Engie, had Sasha, could NOT get more than 32 ammo. Looks like the ammo in reserve is tied to that class's original ammo slot -- e.g., Heavy has 200 minigun rounds, so ANY weapon that spawns in his primary weapons slot will have 200 ammo. I haven't triple checked to make sure this is 100% correct, but I'm positive it's correct at least some of the time
No complaints here, though, other than my rank is dropping faster than the stock market....
