Decapitation makes no blood at all, only a console messae saying 'Attempting to create unknown particle system "blood_decap" ', a very frequent glitch is that the infection spots will be hovering in the air and the zombies will spawn in it for about a split nano second then disapear, the red needle when used on npcs mostly makes them a zombie for a split nano second and then dissapears, consuming is glitchy, very frequently you will become a clusterf*** of weird spike like models instead of a player model and be stuck like this. Even more frequent there is a weapon glitch that literally glitches ALL the weapons. Including physgun, etc. You can't attack primarilly and basicly you have to restart, or be stuck like that.
Console commands (with cheats enabled and disabled) don't work for me.
Zombies spawn underground and under the map.
Swimming is so slow compared to anything else.

Thats all I've found so far, hopefully they can be fixed. Other than those bugs, the mod is excelent.
