I figured out the huts disappearing were in certain locations I assume are in zones huts shouldn't be built. The problem is that it let me place and finish building them. Only to have them disappear and lose resource that they cost after i battle or log out. I've managed to get 90 pop cap reluctantly out of a lot of trial and error and losing many huts.
The main problem I'm having at the moment is the invisible ogres. I've come to notice all ogres are invisible, even the ones in quests , world map , and even ogres that i own. As my human cities and other orc cities I've never had ogres go invisible. This leads me to believe it isn't my computer or graphics settings.
