Magnetometers time out

Hi, I’m currently testing the latest version of arduplane and got myself with strange values on my yaw. I went to check the logs and noticed i got both magnetometers timed out. As a consequence the system was no longer accounting for magnetometers in the EKF as both had failed.
At first I thought about a calibration problem, but then I got the same problem in the simulation environment (XPlane10). (On this case I’m using three on the SITL)Here is an image of the magnetometers time outs. Has anyone come across something similar?
