Position of the Moon 2012vs2015

First pic I made in 2012 when Jupiter was at its closest to the moon:

2012 moon position compared to 2015:

As you can see it rotated quite a bit, no idea if this is normal. Can't remember rotating the 2012 picture 90 degrees, would be a bit strange thing to do. I do remember Jupiter being on the left side of the Moon at that time. I checked the originals in my archive and found nothing strange, I had not made a strange crop or rotated the camera. Apparently the Moon's face has rotated 90 degrees since 2012. I did not know it did that, always thought the Moon rotated around its poles, somewhat like the Earth does, not like this...

Apparantly this almost 90 degrees wobble is normal...
