Ok I go to my house to move things and I cant move my castle blocks,I cant pick them up,move them or,even rotate any of my castle blocks please help.
Try picking it up from the items listed for your house.
Click the housing icon (same one you click to pick up when you're looking at the item). Then click attic. The tabs have attic, backpack and house. Click the 'house' list and it will show you all the items in that area of the house (eg inside or outside - whichever you're standing in). Find the blocks in the list and pick them up from there.
If that doesn't work I'd contact support...but try it first because it was the advice given to me in an auto-response when I had a stuck housing item I couldn't move or pick up and it worked!
