I've noticed that when I edit a sov or unit's "info card" pose and save the new image, the resulting picture in the new info card is of a much lower quality than the image seen in the "edit info card" screen.  For example, skin tone below the neck is a different color, lighting is skewed and pixellation is increased overall.  Is there any way to prevent this?

I've seen this in v1.2A and 1.2F, on three different computers.  And I'm new to the game, so it may be that this is such a petty issue that it just doesn't bother anyone.
