Players get stuck on submerged ladders

[pardner]

Platform,OS: x86_64, linux Fedora 10
Engine/game version: SG v1.0 - v1.1

How to reproduce:

1. Go to back cabin in dm_backwater or under the outhouse in dm_canyon.
2. Jump in the water and swim to the ladder.
3. Try to climb the ladder.

Result:

Once the player reaches the ladder, the player will stick to the ladder and not be able to move up or down.

Expected result:

In WQ3 2.2, the player was able to climb out of the water via the ladders. Its not a big deal in dm_backwater, but this bug has prevented players from using the underground portion of dm_canyon.

If no solution is found, then map re-work will be required to prevent this bug from happening.
