Guided Mode not using BendyRuler

My MR72 radar is working fine with Simple avoidance (in Loiter and Althold) but Bendy ruler is not activating in GUIDED or AUTO mode.

Log attached below:

Have you tried ArduCopter 4.6.0-dev?

I haven’t yet, do the logs suggest OA_DATABASE is the issue? Randy told me there was a bug in 4.5.6 that kept obstacles tracked by the radar being added there but I can’t confirm
