That's not the only bug with ladders though. I haven't seen a changelog with these issues fixed so I take it they're still in the game.

1. When common infected are busy climbing a ladder and a nearby pipe bomb explodes the common infected will stop climbing and get stuck in the ladder.

2. When survivors are standing at the top of a ladder and zombies are climbing up I think survivors shouldn't be able to block ci and si so easily, only tanks seem to be able to push away a blocking survivor.

3. If you shoot a witch and then decide to climb up a ladder and stay in the middle of the ladder the witch will just get stuck at the bottom of the ladder, she won't climb up.

4. Trying to jump off a ladder (default button "space bar") is not always reliable depending on how the ladder is placed (angle).

I've played GunBrain a couple of times. Things that caught my attention: The stats are saved to a specific name and not to players' Steam ID (or am I wrong?). So what happens if players change their names or if players have the same name etc. won't that mess up the stats somehow? I only played on my own server, but is it possible to load old stats from a recently played server when joining a new server?

Seems to be working now, the survivors are receiving their katanas, great.

I placed my map in the L4D2 beta folder for a quick test. Normally in my survival map the survivors start with a melee (katana) instead of dual pistol, however in the L4D2 beta the entity game_player_equip seems to be broken (it's not giving the survivors a melee).

I use a trigger_once (with Output: OnStartTouch, target: game_player_equip, Use) and when the survivors stand inside the trigger_once they should receive a katana from the game_player_equip entity (game_player_equip using SmartEdit, Key/Property Name = katana, Value = 1, Flags = Use Only checked). This setup worked fine in the previous versions of the game, but it's not working in the L4D2 beta.
