In Troyes, if you choose to use a die to place a citizen in one of the buildings, the system asks where you want to get the citizen from -- do you want to hire one for 2 influence? That's makes perfect sense. However, if you don't have the 2 influence needed to hire a new citizen, then you're stuck: you cannot undo your choice of action. Of course, you would like do a completely different action in this situation, but the only choice the BGA UI gives you is to take a citizen from another one of your buildings to fulfill your initial request. 
Here, an undo option would be fantastic, after you remember that you don't have the 2 influence to hire a new citizen. With the current UI, you are punished (by having to lose a potentially valuable citizen worker in a building) for neglecting to check in advance whether you have enough influence to hire a new citizen.
Thanks!
