Did you open all eastereggs? If not, so if you have extra eggs, don’t worry: Those will vanish tonight automatically. You can see the validity date of any inventory item if you tap it in your inventory.
I am sure you all noticed that the clan championship has changed in the way that in the last four weeks we had four different winners. So obviously very motivated managers are indeed able to fight for and win the clan championship, be it with a new joint clan, which is of course totally okay.
Have a great weekend!
