Don't load my custom map when worked correctly

Hello everyone, and first of all, thanks for taking the time to read this.
I’ve been working on a map for about 3 months, starting from a heightmap and a satellite image. I added terrains and assets from other BeamNG.drive maps, and everything was working perfectly.

However, about a week ago, when I try to load the map as usual, it either gets stuck on an infinite loading screen or loads like in the image below — this happens both when launching the game normally and when forcing a reload with F5 while it’s stuck on the loading screen.


In this state, I can press Esc to spawn a vehicle, although it doesn’t load correctly. What’s interesting is that when I click on the “Map” section, that’s the only place where I get an error message, which is the following:


The line of code it refers to belongs to a BeamNG file itself, and it’s the following:



I honestly have no idea what’s going on, but after searching for information online and asking several AIs about what the error and the code might mean, I can guess that the problem could be related to the map not loading the 2D model correctly when it starts — the one that appears in the pause menu — or that the path to the file it needs to work has been deleted for some reason.

Those “paths” or “generated files” required for the world to work properly should be located in my map’s file called “theTerrain.ter”, which I don’t know how to access or how to fix in order to solve the issue.

Everything I’ve said above is just a personal theory with very little foundation about what might be happening, since I don’t really know what the actual problem is or how to fix it. That’s why I’m reaching out for help — I really don’t want to lose 3 months of work and more than 400 hours of effort.
Thank you very much in advance!
