time limited sets

i noticed this year there are time limits for sets like the fantasy and supernatural events for the collectibles but you can still earn tokens in the hut moments which will not expire that is fine but in the fantasy moments you got rewards there for collectibles to still to be earned and that makes no sense if you do not have some kind of set to do something with them after? last year it was a good way to earn rewards even after and event was done why did you change that system? Please put some kind of set to do something with your collectibles you grind for it feels like such a waste of time when you do not specify to people these sets are going to be timed out and you have nothing to do with the stuff you earned by playing but yet you have moments you can do at a later time and you get collectibles that are going to be useless after for a reward! please fix and patch this!
