Caves have invisible ground in New Georgia Map editor?

Hello, FYI I’ve posted this to the subreddit too since I could not upload the video that shows this problem since I cannot upload a video here: “Editor Bug: Caves have invisible ground?”
I also cannot directly link the post

I’ve been working on a custom map on New Georgia where you fight through some of the cave systems. I played through it multiple times and on this point I was able to go in to the cave as normal and what not in multiple playthroughs.

Today I was playing around with adding RendInst assets like houses/windows/doors, etc. and deleted one small building. I cannot think of anything else I change before I noticed this problem:

Now, neither I or AI can actually go into the cave, and end up playing ontop of it. You’ll also see that the nevmesh looks normal but when I use the terraform tool it shows that there is ground about halfway in the large hole? I’ve tried undoing anything and everything I did in the current work session but nothing fixes this. I’ve tried comparing it to a fresh new georgia map but cannot find any differences in any of the caves.

There is actual ground covering all the caves by default and a number of ground_hole_sphere_top_projection+game_object s are used to remove the ground around the cave openings, and they are all still there in my editor, but for whatever reason AI are still colliding and acting like the ground is still there.

Is there 1 single asset/object I might have accidently deleted that causes all ground holes or terrain removers to disable or something?

Thank you for your time and help again apologies for only posting the video in the subreddit, I keep getting errors.

Probably you removed ground_holes_updater and underground_zones_updater.
Entity ground_hole will not work without ground_hole_updater.

Thank you, underground_zones_updater was deleted so I added it back and kept the same default settings. should_update_ground_holes_zones is left unchecked but I tried both checked and unchecked then restarted and relogged but no avail. underground_zones_updater also has the same default settings as an untouched new georgia map in editor. Any other ideas? Thank you for the help so far I would not have found that.

I have both updaters, but collision is not removed:

Even after restart?

Yes.

Ah. Seems something changed since latest major update. Need to turn on level__useGroundHoleCollision property in level entity.

Yeah that solved the collision problem, but if the player moves below the ground it gets teleported to the top

For that need to put there underground zone entity. It will remove teleport effect for some area.
