GCS OpMap: I use GoogleHybrid. Download a section by viewing or ripping. If you get a bad tile or just need to update for a new road or winter/summer, you are stuck with what you have unless you delete the cache and start over.
I have already found and fixed this. It is because the new tiles get downloaded, but the old ones don't get deleted. Displaying just uses the first one it finds, which is the old one.
