If you want, you could try putting this file in /gamemodes/terrortown/gamemode/

Untested, but from what I read about the issue this should make it work.
certain weapons/ammo are completely missing,
Unsure.
weapons float mid-air, knives don't work at all, instant weapon swap/reloading, no weapon animations,
The server is missing CS:S content.
