I would like to have the chance to spend my points even if the event is over. I always collect all the points and spend it all when only a few hours left. The problem is that I often forget the spend my points and it frustrates me so bad that all that point I got is now gone. To specify, when an event is over it will appear when you log in and tells you to spend your remaining points and after your done, you could close it as you normally would and it disappears forever.
If it is possible to make, I would be really glad if you would implement it in upcoming updates.
