Since over a week I have the issue that I can't collect the upgrade from building my Rookery. It is shown in the list but pressing the button does do anything. Now it even blocks the rewards from building walls or other buildings to shown up as this is the recommanded goal for me at the moment. Other rewards are still working fine. I have the account on two devices and both have the same issue, I even logged off and logged in again, but this didn't fix the issue. Any help or solution available? Support did only refer me to the forum.
Thx Lord Wolven
