G'day,
I just turned my christmas market on the highest current level which means 9x9 and +200% Buff. It is currently upgrading to the highest level and the green checkmark was available, so i pressed it and nothing happened. I did take a photo of it, showing the market open and the cooldown time just about 8 minutes after checkmark was pressed. There is no buffs working. I understand this could happen with an upgrade but why have the checkmark available if it cannot be used? Did I spend any resources as well? I did refresh the game to no avail before this message.
