Here's what I did in my last turn
I moved my sovereign
I added 2 huts to my city build queue
I removed 1 hut from the queue
Tried to click ent turn. no luck 
Opened and closed the kingdom panels, still no end of turn 
went back to the main menu and back into the game, still no end turn button 
went back to the main menu, clicked new game (I was thinking about loading my auto save) CTD!!!
Man, they broke the end of turn button!! such sacrilege!!!
