Odd Ground Textures in Nomans Land

[ScottS87]

I am getting some strange ground texture artifacts at specific (repeatable) locations within the Nomans Land map. I have attached one example showing some areas with black tiles (these also occur randomly on pathways as well), as well as within grassy areas the ground itself will have this multi-colored noise/snow type appearance, also circled on my attached screenshot.

I have tried all kinds of graphics settings to see if anything changes. Is this a known bug? Do you recommend me uninstalling Nomans Land and try re-installing it? I am concerned about losing the status of my career there, if I do that though. Is there a way to preserve my current progress on the map, even if I uninstall and re-install?

Thanks!
Scott
