Auto fuel dump when using 'Travel To' fast forwarding in flight A32O Neo & B787

On a couple of occasions now I have experienced a total loss of fuel when using the ‘Travel to’ to fast forward a flight. Once with the A320 Neo, with latest Dev Mod (Heathrow to Dubai -starting with max fuel) and again with the 787 (Faro to Heathrow). There seems to be no recovery with loss of both engines, gens and all displays. Trying to do a refuel using the menu does not work either. Anyone else had this experience?

Apart from the above, the A320 Neo seems far less buggy now & the mod is a godsend, although I find control when landing to be ‘poor’. I am still struggling to master the systems and bugs in the B787!
