I have a mission stating to "Have 5 Bitizen(s) move in" I have built 2 residential levels, the first one I allowed the slots to fill in gradually/ naturally. Once all five bitizens moved in I checked the mission and it didn't register as finished. The second residential level I had used one of my saved VIP's (the Recruiting officer) and filled up the lvl instantly but to no avail. The mission is still not recognizing at finished and requires 5 Bux to skip, which I really do not want to use up if at all possible.

Does anyone know why this is happening and if there is a way to fix it?
