I had a perfectly good (but TS-12 only) grass texture mixture. Then I use the replace assets function to replace one texture with a TS2010-compatible version of THE SAME TEXTURE. I make sure to check the "replace direction and scale" box, but it doesn't work. Now I have a checkerboard ground texture, and the program, for whatever reason, won't let me use undo. So now I have to retexture a huge area.
Avoid using the "replace assets" function with textures!
