We are aware of the issue where, in some missions, the item window gets stuck on screen after opening it. In case you are stuck in the item window, you can remove the overlay by opening any unit's ability window. In addition, you can still finish the quest by tapping on "Auto" or "Repeat" (if you have previous actions done), or quit the mission by tapping on "Menu" > "Give up".

The team is currently investigating the issue. We sincerely apologize for the inconvenience. We will update you as soon as possible.

Thank you for your patience and understanding.
