Some thing odd?

luttrel01.jpg I was going along nicely putting forest textures near the top of the ridges around Luttrel, TN using US2Forest.ace and then for the lower levels in the valley, US2Grass.ace. EXcept for a few sub tiles near the top of the image everything here is US2Grass but somehow this one subtile is much darker than the others. I can change the texture on it, but the darker shade remains. Any idea what causes this, or what I must do to remedy it.

Even odder, I had a need to close the program, so I saved and closed it. A while later when I went back in, that strange looking sub-tile was the same intensity as all of the rest. Later I notice a couple of the oddities and so I closed the program, went back in, and all was normal?
