I am unable to give you information for a specific case, sorry, you will need to contact support so that we can look into. As there are too many variables here (several quest types, buildings you've owned, whether or not the buildings were in your city before or after you opened the quest, time of opening the quest, etc.) it's impossible to provide an answer for anyone on the forum.
The best information we can provide to you as a group is the one that has been provided in the linked announcement thread. Beyond that, you will need to contact support and we'll get back to you as soon as we can get to your ticket and investigate the situation. What we can promise is that if we've made an error we'll work on resolving it.
We understand everyone's frustration, it's not one sided. We're doing the best we can here with a bad situation.
