Every now and then, the magic carpet will continue rotating when you’re holding the right mouse button and move the mouse to look around. I’m sure there’s a combination of factors which trigger it, but it happens very, very often – more often than not.
This never happened with the broom (or Dry Top kites).
It is very annoying when you’ve found a good place and “aligned” your character, but the carpet starts rotating while you’re simply looking around.
