I bought the house in Whiterun so that I could safely store all the stuff I was accumulating. I haven't added any furnishings yet, just used the chest by the bed (mine, not my follower's). Now the dragon bones and scales I left in there are red. Is this a glitch or did I do something wrong? I thought the point of a house was to have safe storage where this didn't happen. Do I have to worry about the chest resetting and removing all my stuff?
A similar thing happened to me when all the pine trees outside of Whiterun turned blue. I just saved, quit the game, and reloaded and everything went back to being fine.
