1. In cvn_coast you can see thru some of the side-mansion's doors from outside. I suppose the prop fadeout distance is smaller than the viewdistance or something, idk.
2. When vamps die, they turn in to ragdolls and then back to vamps if not staked. Now sometimes u get caught in places when you come back alive. Like in cvn_deadship you can get caught between crates, or outside the ship in the water etc...
3. It takes really long time for some humans to change weapons after throwing holy water, a bug or a feature?
4. You can change team in the middle of the round. And the avatar actually does change "sides" but they retain the old teams skin and some abilities. So sometimes u see vampires with shotguns and Slayers that have no guns and run like Fiends, but cant jump like them.
