I played ST Uncut again and I actually found few bugs in the NPCs such as floating headcrabs when I kill zombies. I tried to kill one of the HECU Zombies with a MP5 grenade then I actually seen the Headcrab float while the corpse fall on the floor.
Seirously, it’s like the headcrab floats on thin air. Kinda funny though but still, it’s weird… Same problem as @AlienLizard123s problem… Can you guys fix this please?
