and finally, when I managed to upgrade the gold castle decoration to lvl 3, it somehow disappeared... I upgraded it, replaced it with it - looked at it - keep normal without decoration... restarted the game and since then I don't have gold keep decoration at all... neither lv1,2,3 nor any... I am interested in where, to whom and what I should do and address... because I see that there is an address where I get answers from robots..
