• Take the compas to your hands
• Open it
• Put the compas while its open into your toolbar
• Remove the compas of your hands
• See where North is on your toolbar
• Now take the compas to your hands and check where north is

You'll see 2 differents North directions.

(When you have the compass open in the toolbar and open in in your hands, the direction is the same as each other, however its still both another direction while you only have it open in your toolbar)

I checked it with a different compas and a friend of my checked it with his compas, both have the same bug.
