Crashed while saving - now it won't load!

Long story short - been working 18 hours days the past three days straight on this, annnnd now it won't load. Last backup was 24 hours ago.

"BeamNG.drive 0.15.0.2 0xC0000374 STATUS_HEAP_CORRUPTION"

I had tossed some textures into "terrains" and edited the materials.cs as per usual. Then copied over ground cover assets and didn't change anything else. Opened the material editor, created a new material, applied it to the ground to test it, and when it asked if I wanted to save I hit yes, then it hung, and now it refuses to load my level!! Nooooooooo

PLEASE tell me there's a solution

FWIW it says "building roads" then "import complete" then it goes back to "loading roads" hangs, and crashes with that message.

I went into materials.ca and removed my additions, and in windows explorer just ctrl+z'd the moves that I did, so it's back to the way it was before I copied the textures over (which I've done already 20 times successfully) so I'm pretty sure the save is just corrupt. I'm not sure if I can just copy out the terrain file, or a specific json file or what. So for now I'm going to move it to it's own location in hopes of someone saying, "just remove *.XXX and it'll rebuild itself."

Fingers crossed!!!!

 

Thanks for the suggestion, but that didn't work.

I just noticed that my .ter file has been getting saved in the /levels directory, NOT the /levels/krall directory I've been working in, which MEANS I have no backup. If I delete the .ter file the level loads, but of course. . . without any terrain - WAY too much work to be lost!!!

I want to cry. Grown men . . don't cry.

I can load the level fine if I delete the terrain.ter file, and all my assets - trees, rocks, etc.. are there. But the AI PATHS are completely gone, and the roads and the 20+ hours of work I did on them with it. Let alone the textures, mountains, beaches, tunnels, etc.. there MUST be a way to rectify a garbled .ter file!!!???

It loads roads, says import complete, says loading roads again and 2 seconds later pauses and kicks me out.

I tested this too!! I saw a .ter file in the /levels directory, and I deleted it and it still loaded, I was sure I was backing things up right.

I FOUND ALL THE ROADS AND PATHS! . . at the bottom of the ocean though.

So maybe all I'll have to do is rebuild - the ENTIRE - map again, and try to get everythign as close as it was to line up to all the smoothed roads I made OH MY FRICKIN' GAWD NOOOOO I JUST got my sleep schedule back together. Been going at this for 4 days hard, 3pm to 10am every day and today I skipped sleep to be "normal" for Christmas. My heart aches :'(
