Hi james.
my floors that I design and I add to the design as i add things to the floor. Twice now I had doorways with 1cp tiles extending in. so approx. 28 tiles at 1 cp. and the rest of the flooring was the light tan free cp tile. After the update, (which my first occurrance was with black and teal (1cp teal speckles) at gemstone. anyway to make this NOT confusing. i have laid down more 1cp tiles around objects, to blend in with my sand floor. (example of sand mixing, any of my sandstone casinos) anyway as in this picture these are the new tiles i placed since the update, and upon saving all my tan tiles and THE previous 1cp tiles in the doorway all turned white. At first they were blue until i refreshed now white. http://prntscr.com/c40h8r now I have to redue the entire floor around the sand tiles (1cp) and replace the tiles again into the doorway. This is the second time. the first time i just though it was me, and replaced all the cp tiles in my gemstone, 3rd floor.
