[Observium] Discovery on Nexus 3K removes all interfaces

I am running 0.15.3.6350 and have noticed that some time ago all interfaces on my nexus 3k's gets marked deleted every time discovery runs. However the interfaces are not deleted.. :/

I have done debugging on the a discovery and the only problems I can find are these (I am not sure these are related at all):
