Other probably relevant data: Mod configuration has not been changed from default, and I play the game in Spanish.

First of all, I want to say thank you for making the mod. I’ve been using it since I started playing a few months ago in version 1.5.

I’ve encountered a critical bug that affects save files with a corresponding cave map.
Here’s what happened:

I had a cave map in critical stability status filled with toxic pollution. I took a pawn that was inside it to the surface and proceeded to draft them in order to destroy the cave entrance. I then switched my camera to the cave map, and as it was collapsing and causing a cave-in, the moment the map deleted itself, suddenly the surface map was instantly affected by pollution, earthquakes, and collapses were applied across the entire surface, as if the cave’s internal conditions had spread outward, effectively destroying the surface map.

Below is a list of the different behaviors I encountered while trying to debug:

Loading any save file that contains the cave map before the cave-in will have its entrance and exit removed. If there are any pawns inside the cave map, they’ll be unable to exit unless using the “reform caravan from map” command. In such save files, as soon as the cave-in happens, the same problem occurs (pollution spread all over the surface map and multiple collapses).
Loading any save file before the cave entrance/map is created seems to work properly. I had created other caves previously in this same save, and they worked as intended.
No errors are logged in the console when the problem occurs—not even in Dev Mode.

I’ve checked the HugsLib log myself, and to be honest, I didn’t find any relevant data that could help pinpoint the issue. I understand that identifying the cause is difficult, and there’s always a possibility it’s due to incompatibilities with other mods. Regardless, I wanted to report the bug in hopes it helps. If you need any extra information, i’m more than willing to help.
