Invisible zombie bug

[ShadowStalker™]

While going for a run round 100 on Revelations I encountered an invisible zombie 3 times.
I could hear him so i knew where he actually was and i confirmed that it is an invisible zombie by letting him hit me while no visible zombie is around me(I also tried to knife him but it didnt work).
That might be some bug idk and the only thing that killed him (since i could only hear him and not see him) was the Apotication Servant.

well this issue has happened a few times for me but those times i wasnt able to kill it, the only way i could kill it was to let it respawn somewhere else and then kill it, this happened to me all the time while training in the "pack monster" so i had to exit that and let it respawn outside..

Try killing him with the Apotication Servant.
It did work for me

I didn't know what to do with the invisible zombie. It wouldn't even attack me
