Strange Wookong issue

I am hoping someone here can shed some light on a issue I am having with my Skyjib 8 v2 with Wookong. We have been testing some movi gimbal changes today and the aircraft was behaving very strange. In GPS when flying forward the aircraft would fly straight for about 40m and then aggressively via to the left. I have tried calibrating the compass as well as changing the direction of the compass. Changing the inclination of the compass would add drift to the aircraft as you would expect but would still via to the left after about 40m. I am running the latest wookong firmware. Any ideas?
 


I trust you are keeping the configuration simple and not implementing the built-in DJI gimbal control as this has been known to cause issues with flight control under certain conditions such as switching back and forth between gimbal control and RC remote gains control.
There have also be some issues with the newer WKM firmware so I have stuck with fw version 5.20 and have avoided moving forward to newer versions. To date I have over 100 successful flight w/o incident provided I avoid above mentioned gimbal control

BGC system use their own IMU which isolates BGC issues from DJI FC issues.

Im just thinking out loud here but somethings that could be the issue:

Lateral limit set in WKM assistant
Radio mast near by causing GPS interference
Groundstation plugged into WKM (shouldn't cause this but you never know)
Flying near Tianaman square?

Yes I have kept things simple, we flew the aircraft without the gimbal and had the same problem. I have disabled the limits bothe lateral and height and even tried knocking IOC off. No ground station was plugged in and I don't think we were in China! Everything seemed fine in atti mode. I wondered if the imu maybe faulty, could a faulty imu cause this? The area we test in is rural with no power lines or radio masts.

If it worked fine in Atti it wont be the IMU. This also starts to point the finger towards a GPS issue.
