When I played Midgard and game got advanced, it happened to me at least every second turn. Now in Eight Kingdoms, twice in row, again. I don't much notice if it happens when I have not many units, since it is not much a problem, but having start to cycle through my 250 units again after reload is bad... It would be nice if the game could remember groupings and setting units in attention even if the screen was reloaded, or game left for a while during turn, it would make the long turns much more comfortable, and this bug would be only very minor problem
