It would be great to have a Confirm Turn button that if you instead Cancel takes you back to the start of your turn.
I am on the last year of a turn based game, and I clicked to purchase a Spear Hut that I can't place in a village because it already has a Spear Hut. Now the game is waiting for me to place it, but I want to cancel the purchase.
This will completely ruin my last turn of a game that has been going for many days.
Anyway, enough tears; but it would be a great feature to avoid future pain.
