Seems the plugin stops working after a while (Spitter, Smoker and Tank do not move anymore), not sure what's causing the problem, as i didn't find any errors in the logs.
Are you using the latest version? Does this happen after map change? How often does it bug out? Have you changed any cvars? I can't replicate the issue or see what might be causing it. Maybe a plugin conflict, do you have anything modifying players m_flMaxspeed?
