I hope you don't mind I made a video testing your code to show you what happens to me.
(On my youtube account I have the video settings as private/unlisted, just in case you don't want anyone else to see this yet. The only way to watch the video is following this link in the forums, no search on youtube will list this video)

In the video you can see bots get stuck, and at the end the problem with death-cam and not respawning.
Also, every once in while it seems I am getting "pushed up" or something and bots start to work again. Is that what you added in this version?

Still needs some work, but it's a nice start.

P.S: I added a couple rock/metal versions of doom and dukenukem songs in the video for fun, enjoy!
