Grace Period to collect event rewards

Tdactyl

Please start adding a 30 minute or hour (or a bit more) grace period to collect completed rewards at the end of an event. I had to work on getting the last two dragons on this one just to finish up to the last minute and then couldn't collect the rewards.

When we have to use our potions to even get any traces at our locations, its not cool to then not even be able to collect.
