Thanks for the reply. I always load the FPL into the EFB as one of the first things after starting a flight. However, I usually manually type in my airways/waypoints, so I don't use the flightplan import in FMS. So I fill in INI page 1 then I fill in SID, waypoints, STAR and then I go to INI page 2, fill fuel block, ZFW and when entering the ZFWCG from the EFB weight&balance page game over, blank FMS and restart the flight. It has never happened to me pre 1.0.3.
