I've had 3 weird instances (or rather where I noticed it at least).

1. There was an offering to spawn the hatch at shack, the survivor is injured as the 3rd one is being taken by the entity, and instead of running around the shack, he stays in one spot. The hatch spawns as soon as I down him and he crawls through it during my cooldown. Does the hatch always spawn in the same location with the offering?

2. 2 survivors left, down one and I see the last so I give chase, hook the last, go to grab the third, who has now crawled toward me actually but stopped moving when I arrived. I picked them up and the hatch spawned right where they were lying.

3. Same as above but I decided to let the last survivor go, I let them wiggle out and the beeline for the hatch. I thought maybe they had a map or whatever, but I couldn't see a reason.

It makes me wonder if that might be a thing people do?

Other than the hatch, I hadn't noticed any weird things with those above mentioned stories.
