0:28 you can see I killed the guy but in 1:41 you can see it's affected by bile (for some reason its the only prop affected by it)
I was playing this map with one other person (I didn't know them) then the glitch started happening (prob for rage quitting due to the bs the game director throws at us)
I threw the bile cuz you can check for ambushing special infected
No, common infected are supposed to spawn and there are no mutations as of this edit
