But for the record, what do they do anyway? I've never seen any corresponding icon for any planetary improvements for the 'water-drop'let.
The bonus tile icons don't directly correspond to the ability icons that they affect. Anyway, this one in particular boosts the effects of morale improvements.
Usually early in the game, a fatal error occurs if an approval tile is clicked on to scroll down to see additional information - I'm sure the solution will be DON'T TOUCH IT THEN!
Please open your debug.err file in notepad, and copy/paste the contents into a post here. This will give us some technical information that can help troubleshoot your problem. The location you'll find the debug.err in varies depending on your game version:
Dread Lords, all versions: C:\Program Files\Stardock\Totalgaming\GalCiv2
Dark Avatar 1.5-1.6 (non-Vista): C:\Program Files\Stardock\Totalgaming\GalCiv2\DarkAvatar
Dark Avatar 1.6+(Windows Vista), 1.7+(non-Vista):My Documents\My Games\GC2DarkAvatar
Twilight of the Arnor:My Documents\My Games\GC2TwilightArnor
Be sure to copy the debug
immediately after the error occurs; if you start the game again, the debug will be erased and recreated for the new session.
