Map mod problems

Where does Beam keep the most recent changes to maps?
I went to work on glass view mountains again and decided to clean it up first since i had an old version in "Documents\BeamNG.drive\levels\glass_view_mountains", and a newer version in "Documents\BeamNG.drive\mods\levels\glass_view_mountains".
But as soon as i got rid of the old version, it started to load a different old version(that i can't find) and i can't seem to get it to load the most recent one.
i have tried looking through the caches of previous versions but they only seem to only have the art folder.

 

Saving a map in the editor saves it to Documents\BeamNG.drive\levels\, so the version in there was likely to be the newest version.

 

Thats what i thought, but when i checked the "date modified" it was 4 months older than the other one, and neither of them were the latest version of my map.
Also when i delete one of them it comes up with the error "failed to create resource" even though i have that resource in the art folder.
Thank you for the reply anyway, much appreciated

So i just done a search through my whole computer, and the latest version of my map seems to be from the 25/12/2015, even though i had modified, saved and backed up since then. So some how since then beam has been saving to an unknown location and has somehow deleted all the work on my map since then
I also just checked another map that i know i have edited this year, and it still says that it was last modified 25/12/2015, and there is only one copy of this map on my pc

 

What file are you looking at for the modification date, the .mis file?

 

That and the .ter, which are the most recently modified files.

 

Have you made modifications to your map and looked at the new saved .mis in documents immediately after saving?
That shows the old date?

 

I just tried going in and changing something then saving, the .ter says that it was last modified today but the .forest still says it was modified last year even though i modified it a few months ago, even the .mis is still out of date so i have no idea where it is loading from.

I think i am just going to have to start from the most recent one i can find
