When i was going down stairs in the modern masion it took for ever and when i was down everything was all glitched and in a corner and when i went back upstairs EVERYTHING was deleted and i spent an hour re-building everything and another hour to go get all the items from all the places and put everything where it needed to be and when i did everything it took me about 2 hours and a half to do i went bak down stairs and back upstais again it was all deleted again. I have spent so much money.
