[0.99.24] PCs and Mobs able to clip through giant cylindrical structure Mourn is built into

[Argus]

Crash Dump:

Not causing the game to crash, but it is allowing Beak Things into town incredibly easily, decimating the population and making it hard to rest in town.

I've included a zipped folder of some of the text files that would be included in a crash dump, though.

What Happened:

Went to Mourn, fought some Beak Things outside the walls, got a bit beat up, so I went and rested at Camp beds along the wall of the cylindrical structure Mourn is built inside of.

After fast-forwarding for a bit, I noticed Beak Things clipping through the walls to attack my resting PCs.

After killing them, I tested with my PCs and was able to have them clip through the walls repeatedly. I then exited the game, verified files on Steam, reacquired 3 files, and tested again, and was still able to clip through the walls.

I also had noted earlier that the giant bones between Catun and Mourn could be clipped through, but thought this was some sort of aesthetic choice by the developer, not a bug.

Consistency:

Only tested on the 1 save file, but as I said above, I could do it repeatedly with PCs, even after verifying files on Steam and restarting the game.

EDIT: I could also still do it after doing the CTRL+SHIFT+F11 navmesh fix.

Mods:

I am using one mod, In-Game Biome Map (No Colour) by Shidan, on the Steam workshop.
