I've lost count of how many disappeared. The problem for me is that the ones more likely to disappear are the low levels. I once lost 2 level 5 business centers but unfortunately they came back. Because of this, I'm waaay over the limit regarding some buildings like the Modern Mansion, that I got 18 of them all level 5, that is one of the things that allowed me not needing to level up some others to get to the billion.
