Android I completed a set, but I can't find the chest in the selection list...

[Bertron]

I am not sure if I am going about this the wrong way, but I completed a set when I was visiting other players' cities, but was distracted with other things before I went to claim my chest. When I click on the chest icon with the exclamation mark, it doesn't immediately take me to the prize for the set that I completed. I don't think I can go through all of the lists of sets. Is there a quick way to go through this? I feel like I'm missing something here...

Thanks for the help

Sorry - the last update broke the collections. If you remember any part of what it might be, you can try doing a search for it. Just use the first tab while searching. (the one with the 221 collections) Otherwise, just scroll through. Hoping this gets fixed sometime soon.

I tried your approach and searched for items dropped in planetariums and sure enough I wound up at the collection I had earned. Thanks for the advice

Items dropped from planetariums can be found using the rocket icon.
There is only 95 collections. red launch items are usually found 2/3 rds of the way down.
