Unfortunately, we can't cancel the players' actions or change them in any way!
We understand that sometimes it is possible to perform an action not on purpose. Still, game progress depends on players' actions. We can't cancel them, because it would be unfair to other players, that can also make mistakes.
For example, if we cancel the selling of items, the game balance will be broken because it is possible to sell them for a higher price.
Or if we cancel the action at the Festival, some players can cheat. Thus, the entrepreneurial spirit will be lost, there will be no need to think over your steps, and it will be boring to run a coffee business!
We kindly ask our players to be attentive to in-game actions and not skip dialogues with customers. In this case, you will not miss essential plot moments :)
