Hiya Guys, I have a flight planned today and have 4 Litchi missions planned to film it. Two of the four go off perfectly without a hitch. But the other two, when I load the mission then press start, it brings up the usual box of the mission preview, but the "Go" button is grey instead of blue and will not let me start mission. This is while I am in F mode and have just ran the other 2 missions just fine. I have checked the mission settings from the mission hub and everything looks fine. Any ideas??
