Is it wrong that I've never had any house related bugs?

If you've began a new game since Dawnguard, then you will encounter the alchemy lab glitch when you buy Breezehome, if you played prior to a certain patch and attempted to place books you would have encountered the books disappearing, if you drop items from your inventory onto the floor of any house, then proceed to handle them, things will go flying in all directions and so on.
The fact you haven't encountered any thus far simply means you didn't or haven't done any of the above. Other than the bookcase glitch, the things mentioned above still happen. Then you have/had the house in Windhelm. That was a complete nightmare. I dunno if that's even been fixed yet.
