Is this considered as an exploit?
I've saw a post where man said that Ghost Face by stalking is able to go inside a hooked Survivor.
While stalking, the Killer loses its collision completely as long as he is stalking. When the Killer stops doing it - he retains the collision. I've tried this and yeah, when inside a hooked Survivor, the Killer's collision prevents the hooked Survivor totally from being rescued. Nothing may help is such situation.
Devs, will you ban people for doing that? Strangely, this is as strong as facecamping leatherface, but on any Killer.
