Losing RAW clip when 5dmk3 HDMI out is interupted

[TjS]

Hi guys -

I am flying a 5d mk3 with ML on an octocopter and use a Nyrius Aries Pro (same as the Paralinx Arrow) via the HDMI out as a wireless video downlink. 
My problem is that every time I fly out of range (max. 300 feet) and the Nyrius loses its connection, the RAW recording stops and the whole clip is lost. For some reason ML does not save anything in this case.

To fix this problem I looped a SmallHD DP4 monitor inbetween - so even if the wireless signal is lost, the camera is still sending an HDMI out to the monitor and doesnt stop recording or loses the clip.

My question is - is there any way to fix this from the ML side of things? 

Thanks,
Tim
