I have a fly away problem in loiter, AC 3.0.1, and I've seen that there is a misleading issue with my external compass HMC5883 (3dr robotics). The arrow silkscreened shows an incorrect direction.
I don't know if that corrects my fly away problem, but the true is that I have compass_orient parameter = 0 (not correct).
I will test tomorrow.
Please, advise at wiki.
This is APM 2.5 (see compass IC code and arrow)

another one with wrong dir.

In this model you have to follow the big arrow.
