Do world objects reset?
Solution 1:
Take a peek at UESP's Housing page and you can find a list of overworld 'houses' that have safe storage in them. However, I do not believe this would keep things placed on a table or a chair from resetting when that cell resets. (I even have problems getting things inside of a normal house to stay put!). At the very least I would expect you to find things in disarray when returning after a reset has happened.
