My friends and I have been trying to play prop hunt together in a private server hosted locally by myself, but we continue to run into a frustrating set of problems. After one or two rounds of playing, the hunters stop taking damage from hitting non-player props. Not only that, but the rounds stop switching over after all of the player-props are killed, or when the time runs out, essentially making the game unplayable.

Are there any other instances of this happening elsewhere? Any thoughts or solutions would be appreciated.
