• Went to the "Rescue Drodin" quest and lost the battle with my (admittedly) weak army. Went back with my stronger stack and fought the "Kidnapper" stack, winning the fight. The unit Drodin that you're supposed to get as a result then appeared on the strategic map, but I was unable to select him or have him join an army. He then disappeared the next turn. 
• I have a save that I sent Scott in which I loaded a perfectly normal save game and the entire map was revealed. When I loaded the game, it immediately flashed to the "Buried Hero" quest and I "paid my respects" to him and then BOOM, no fog of war at all. Reloading earlier saves doesn't change anything, for some reason.

I'll keep adding to this thread as I play more.
