I know there's a way to turn off the "flying" graphics from collecting which might help if you haven't already changed it. I will probably use Co-Op and hope for gift eggs to be my missing dragons. I really don't want to use my wishes on them - would rather save those for islands. I purchased the new building but haven't played around with it too much - maybe next week while I'm on vacation. I also purchased the two dragons that have been around the whole event but I've only managed to breed one of the Golden hybrids.
