TC Replacing Player Sounds - Crashing?

[ShortBrass]

Then it seems to be just my game.
I'll do more research on, whats causes the problem.

And thank you for pointing me out. The crouching height is actually a test. I was kinda playing around with different settings.

Oh one last question:
What could it be, that my game isn't able to create caches for some maps?
(ERROR: Could not map cache file 'path/file.map'.)
