you still can but you have to wait untill the castle is fully loaded and dont click on the gold goblin itself you have to move your currsor around it until it gets the blue glow around the goblin..... always happens when we get the extra click thingy's 

today can not click on Goblin's Gold in Friends castle, iron and food are normal
