After sometime the texture of a mesh randomly changes

After sometime the texture of a mesh randomly changes
The mesh didnt have any green and yellow color a while ago, but now it started showing up.
I cant show any pictures of the mesh without the green and yellow on top since it always appears to have some. even though when i textured it in blender, it had no yellow green colors
(the texture map does have the color yellow and green, but i didnt texture it like that)

After:

How can i fix this?

I doubled the pixels in the texture map and it works
