It's not uncommon for magnetic compasses using a simple mechanical mechanism to fail to rotate when the housing is tilted past a certain limit. The force imparted by the Earth's magnetic field is mighty weak, and it doesn't require much friction to cause the card to 'bind'. Moreover, larger tilts also weaken the torquing force of the magnetic field.

Compasses of the gyro and repeating type don't suffer the same limitations (although other limits may be in effect.)

Should a gentle 50 degree aileron turn in order to follow a waypoint lead to the compass sticking after about 5 degrees ? I understand but I don't see the same compass behavior in any other version of the game or the stock game. I noticed this thread and read through it and wondered if there were other oddities as I generally find Cassie to be extremely well sorted.

in a lot of the Fw-190's that in a flat banked turn the cockpit compass sticks at a certain point and will only flick to your current heading once you level the plane out again

That's intentional.
At pitch/bank angles higher than 15~20 degrees (depends on the aircraft model) parts of a magnetic compass touch the casing and the compass, depending on it's construction, becomes unreliable or completely stuck.
In slaved mother/daughter compass installations (which is usually the case in aircraft), usually the daughter compass gets artificially stuck in this case to avoid misinterpretations by the pilot.
