Can't Save My Work In The Map Editor

I am trying to make a rallycross track on some of the stock maps, hopefully I can post them and other people can use them. But the new update made it so that I can't save my 4+ hours of work in the map editor adding road barriers and jumps, of course I figured this out the hard way (Spending 5 hours on my laptop [Yes LAPTOP] to try to make a track in JRI, Jungle Rock Island) which WASN'T FUN AT ALL, the first thing I thought was, maybe it didn't save because JRI is a WIP, Work In Progress map but when I tried Small Island, USA it STILL DIDN'T SAVE. So now I'm stuck. If you know a way to save work in the map editor I would ​GREATLY APPRECIATE the help and if there is no way...

Dear BeamNG Drive Developers,

Please fix this issue ASAP because it is VERY VERY ANNOYING.

Sincerely,

Looked at any of the many tutorials around? If not you need to look at Mecke96's series. It's way more than just saving and playing.
