I would like to add this both special rules for the map zpo_bloody_winter:
1. It is allowed to stay in the generator house on the generator!
Since you don't need a prop to get up on the generator it is allowed as human to stay on it. As admin you aren't allowed to punish a player who stay on it.
2. It isn't allowed to stay on the balk from the treehouse!
This balk isn't reachable for zombies when they get shoot from the humans. As admin you are allowed to slap the human down from it.
