VU+ Duo2 running 5.0.013, with tuners connected to a fixed and a movable dish - everything fine.

I allowed it to upgrade to 5.0.014. After that, any attempt to tune a channel on the movable dish gives (after a pause):

No data on transponder!
(Timeout reading PAT)

The fixed dish seems fine.

I restored an image backup of 5.0.013 that I had just taken, and everything is working fine again.

Is there a known issue with this update? If not, how can I help you diagnose the problem?
