Terrain Layers Changed

Hi,

I am experiencing an odd situation - My terrain swaps layers/colors after I close the project.
The new layers and colors keep the same colored pattern on the ground, but everything is now made up of unknown materials and layers, that I did not add to the terrain paint texture. Yes - I've saved the project and double checked everything.

Kindly see attached photos. terr1 is before (what I want) and terr2 is after I close the project.

Any advice on why this is happening and how to solve this will be appreciated!

Thank you!

 

Issue fixed!
Was using Microsplat asset package - Confirmed by the developer that there was an issue where layers swapped automatically. Is now fixed with the 13.04.21 update.

But what about the damage done?
To reverse the layers I simply went in and one by one replaced the layers back to original layer. All my old layers were saved automatically as layer 1, layer 2 etc.
