It might struggle on for a while, but eventually it will fail completely. The games assets could be fine, but your GPU is failing to load/calculate things properly. If the above doesn't work, or you see more strange graphical artifacts, it could be that your GPU is dying. It could be a symptom of something more serious Alternatively, you can uninstall/reinstall the game, but you should take care to manually copy your savegames to a backup directory. If you're playing on PC/Steam, I'd suggest going into your game properties and hitting ' Verify integrity of game cache.' This will look through your game directory and re-download any missing or corrupted files. If you've uninstalled all mods and still see purple bushes, this could very well be the problem. It could be that some of your mods over-wrote core game assets, and the textures are missing from the game files. If an image resource can't be located the game will color the object purple in its stead. In a lot of game engines purple is a kind of null-color. Purple stuff normally means missing textures
