First of all, a high on the reviews here! So I already knew before purchasing that there is an error in the assembly instructions and I do not need to doubt myself. So Christmas was saved! In principle, work both solutions described here: reposition the rock on the tower is simpler. But it has the disadvantage that it is the folding ladder leads nowhere. The other solution is to swap the two corner pieces left of the castle gate. But but you have to cut a small ridge with a paper cutter or a sharp paring knife. Since the material is very soft, it does not present any major problems. The ready built castle is very beautiful, there are many things to play, not only warfare.
