~Mega-Lo-Mania Problems with Hibernation ? Information obtained via Netmail. From about the seventh epoch (Ithink) you can do it. Go into the defense screen at the castle you wish to hibernate and if you can do it then there should be another icon to click on (looks a bit like a womans head) and click on it. It is late on in the game and don't forget to leave at least one of your castles free otherwise you lose the island. Try to put 999 me into the castle before you do it though, as I once had almost 3000 men frozen in one game but still ended up with only a handful in the mother battle. Mark.
