MED: Tunnels

[Oscarmike247]

I cannot seem to figure out why my tunnel sections are not working. When you're in any given section of the tunnel, all other sections disappear. You know the usual tunnel bug.

I've set up many tunnels before, and yes you run into this sometimes, but usually there is something not aligned correctly or an interior object causing something weird. This time, I cannot figure out why they're not working. They work initially, then without moving them, placing objects in them or editing ANYTHING about them, they will suddenly stop working. and once they stop, they don't start working again.

worth noting:
-There are no objects or AI in the tunnel.
-The tunnel is very small, just one entrance, a hallway and a small room with end caps blocking the other 3 doorways.
-This is in stock JO:E. No mods.

What I've tried:
-Made sure the tunnels are perfectly aligned using a 1m grid snap, their z values are all the exact same, no rotation.

-I also placed the sections by inserting, not copying, as I read somewhere that copying can cause issues.

-I tried moving the tunnel so the entrance is more underground. Hell, I even started over with a different tunnel entrance on a flat terrain.

-I tried editing the objects in the .mis file using notepad to set up the blink box groups. Which seemed to work at first, then as before, after re loading the game a few times, it stops working. I checked the .mis file in notepad to be sure all of my "blink_group_a 1" were still there and didn't get overwritten by the med.

Is there something I'm missing?? It's just strange that when I place them initially they work fine, but if I close the map/game and load back into it, some of them start disappearing, then eventually they will all stop working.

Thanks for any help.
