Trains, sometimes tracks, and the various machines are stuck as full black. Sometimes the models just phase out and are invisible but from certain angles they pop back in, sometimes they have textures but only for a second or 2. I tried clearing the cache but that didn't help. I can interact with everything fine its just the textures being broken. I tried using the paintbrush to see if certain textures were broken but it seems to be a model issue. The models are more stable when in the inventory but still have the same issue.
