How to I save edited map into new file?

So I loaded up gridmap and changed it, pressed save as, picked my location and saved AS. Did not worry about it and kept saving (just save) as I edited along.
Today when I wanted to pick it back up and continue I found out that save as did literately nothing, also that my gridmap became the map I made.

I don't mind destroying gridmap I don't use it but I tried saving as and it does nothing like nothing happens, I select the location and type in file name no new files appear. I can export hightmap that does create an export so I know it's not folder or file access issue.
Also it creates .level.json.level_0.ter and .level.json.level_0.terrain.json files but not in the specified directory, it goes to \levels instead no matter where I try to put it.

Additionally when I press save as all the hitboxes for terrain stop working - cars go through the ground, but it all loads up OK if I load the map again...

How can I export my progress? I just want to save map as a different name so the new update or whatever does not erase it by modifying gridmap to a new version.

I wanted to simply copy gridmap files and rename them but I can't find that also like WTF??
My /levels/gridmap folder is 10.2 KB (10.458 bytes) big, that can't be it? How do I get like zip file for gridmap like mods have and just rename it or something

This is driving me insane, I feel like I just wasted hours of work on a map that I can not actually save as NOT gridmap...

Thank you for help

 

Were you using the old editor? I tried out editing gridmap in the new editor (F10) and had some quite different issues.

First I tried to save directly to \My Documents\BeamNG.drive\levels\ instead of creating a subfolder, which was a bad idea.

On the next attempt I saved my map as \My Documents\BeamNG.drive\levels\gridmap_edit\ and this name really messed things up. Instead of putting the original files to that folder, they were unpacked to \gridmap_edit_edit\ and so loading gridmap_edit gave me the map with no textures and things. I think I'm on the right track now though!

It'd be great if the editor could create \My Documents\BeamNG.drive\levels\ if it doesn't exist yet, and default to that instead of a folder in steamapps.
