Anyone having this problem starting a new map ?

Pardon my French in this, hehe. Love the game BTW !
Problem with Terrain being saved. - YouTube
Import Terrain...

Imports fine..
Reload level after saving level.....I am assuming is has to do with nobody being able to save terrain materials pending PBR 1.5 for weeks now somehow also interfering with terrain block creation. And its not just importing an exported terrain. Making a new terrain block does the same thing. This map East_Coast before deleting most everything if that matters at all.
Seems like this happens reload the entire game not exiting level and reloading from main menu. Or its very random if it works or dont. Sometimes it loads right, sometime not.
Since this issue is not happening on my other maps. I am about 50% sure I did something wrong. Deleted something I was not suppose too. But it is the first new map I tried to make since the save lockout on terrain materials so has me wandering if its related. Thanks in advance to anyone responding. Not that big a deal, I got plenty other things I can be working on other than this map.

 

Me and some friends decided East Coast just has issues when converting. Template map just does not have enough stuff on it. I would think there would be a better template map for modders to use that the devs could make in a later build. One with trees, more than 2 terrain paints, some meshes ect...

 

The level was made by using the program find and replace to change out all the \levels\east_coast_usa
to \levels\mynewmap for example.

Then deleted the terrain block and created a new one the first attempt. After painting it with terrain paint and coming back the textures where gone.
I then deleted that block and imported an export from another map of mine through terrain tools import. It imported fine, textures where right... But after reloaded the game the textures where gone. Not missing or No Texture, just greyish green.
