Isn't it clear why the delay? In order not to collect silver from the chests in the "Colosseum". Now, it's not a problem to reach the mystical map, especially if you go through the entire "Colliseum," without taking into account the chest for 20k points and tasks with cards. The only thing that takes a lot of time in the event for me personally is the tasks for collecting 25 and 45 event cards, well, you can add 2000k silver here, and everything is quite fast enough to collect resources completely from 2-3 times in the "Colliseum"
