the problem is not how much it really costs but that the players build their walls starting from yours and changing direction.

how dare them ? xD

nono it works, except sometimes.try to die or reload the page.

same experience.

i know there isn't a easy solution but isn't funny not being  able to build your castle because some noob comes and starts building from your walls.

i do not like the idea, now come now the are more ways of development and it makes the game more varied and perhaps group work.
