Lost fairy dust and boosters

Help needed please. I completed 2 new rounds of updates on my house for which I received a stereo bolt  and a sparkling blast, neither of which appeared in my game. And during the first round of house updates I changed from playing on my laptop to using my iPad. When I went back to my laptop later the 2 updates I had made to the house had vanished, and I had to spend another 6000 fairy dust to upgrade them again. So that means I not only lost the 6000 fairy dust but I didn't get the boosters either. And I now feel that I can't play on my iPad in case I lose all the house upgrades.
