Wall Artifacting

@Staplergun if I understand you correctly, this glitch is only occurring with one particular build?  If so, is this a build of your own creation or one you downloaded from the Gallery?  If your own creation, would it be possible for you to upload it (just call it "Test Walls Glitch" or the like), and provide me with the link or name?  If someone else's, I'd also like to take a look at it, if you can let me know the name or Origin ID of its creator.  Also, I understand that you don't use mods/CC, but corruption can still occur in the game.  If you haven't already, please take the following steps: 1) clear your cache, 2) repair the game via Origin, 3) start a new save, and 4) test the build in that new save (if you haven't already, save the build to the Library so that you can easily place it into a new save).
