They wont tell you it cant be done. ;) Cause it COULD be done. It just wont. ;)

See, every single thing in this game, from "moving your town 5 feet north" and "make your troops walk a liiitle faster than snails" up to "attack other players and need to re-shield" costs money.

Building and re-building, too, costs money and therefore makes them money. 

Yeh I but they could add this thing to a gold pack. They make money and we save money. Although i know that they probs ain't going to bring that into the game it's worth a try. It will be funny when in future they'll get less attention for same s*** happening over and over. Players are already complaining how lower lvl cities have no chance since as soon as they hit lvl13 they will be wiped. 

For what real reason do you need this function? In addition to aesthetic of course.

Dear Jarl,

Unfortunately, this function is not available in the game.

Best regards,
