In that case you're talking about the landscape texture file for the paved roads. The UOP does not alter this texture, so your problem likely came from a faulty texture replacement.
If that's not it, could you take a screenshot of what you're talking about?
I really wish I could see a picture. I am thinking BSA Redirection too.
OP, if you use OBMM, set BSA Redirection in OBMM > Utilities > Archive invalidation
Also, if you have an ArchiveInvalidation.txt file in your Data folder, delete it.
