Could be a issue with the "addon". I played Headcrab on Black Mesa RP and had this issue where you move quite fast until you press shift again I think , which resets the speed.
Yeah, it's quite annoying especially when dispenser refused to give out ammo because it's out of stock and some operation is about to come up, or there is possible shootout about to happen.
I used to play HL2RP on Helix mostly, rarely on Clockwork and one thing I noticed is that when characters walk they slide slighlty. Looks quite weird.
On Helix no matter what speed you set animations would follow. Not sure how it works on CW.
So I found an addon that could maybe work ...
