I am having the same issue with orcs space is blank, except in battles where it shows my paladin in the pace where the orcs should be, and have been for a while now. In addition it is getting a lot worse as each day passes. Now when I set buildings to upgrade they disappear until I reload the game. Also loading the game is taking longer and longer.. it is getting stuck at the reolad 25/28 for several minutes. Since I have switched from flash to html5 I can't find where I can clear my cache other than my browser cache. It doesn't seem to matter which browser I am using, they are all showing the same issue.
