Sorry if I wasn't more clear. I'll try to explain again.
In the first image displayed, the tileset.png is the default. Under the trees are the normal grass and dirt tiles.
However, in the second image, the tileset.png is modified. Under the trees are mostly snow tiles. The snowy grass and dirt tiles are almost white, but whenever I load the game, green "blobs" appear over those tiles. In my case, the green area in the center of the second image should be white instead of green.

That's the problem. I've changed the grass tile to look almost white in color. But the game continues to place green coloring.
When running the game in safe mode, these green "blobs" don't appear, along with the lightmaps.
