Excellent game, all around.

Technical information: GC2:DA (Most current update)
I am currently playing all the races, just to see what they can do, what they are capable of, etc. As it so happens, I tend to research like mad before building up my fleet. With most races this is not an issue; however....
I decided to play the Korath Clan. I am playing Cakewalk (so I may get a feel for the new rules, programming, etc.) and there I was, building up my civilization, when I started noticing my Approval rating going down (At one point I was 92%; about 20-30 turns later I was down to 82%). I checked my colonies and discovered a few of them were below 40% approval! I started placing Morale+ buildings like mad, but it doesn't seem to affect it by any appreciable amount. My Morale is dropping steadily and I can't seem to get it on a positive curve.
[Several of my planets had twice as many Morale+ buildings than Food Production; I have found that a 1 Food for 1 Morale ratio tends to suffice for Good/Neutral civilizations while a 1 for 2 works for Evil civs. It may be just the way I play. *Shrugs*]
Now, most real-life democracies have a "war weariness" threshold; i.e.; the point in any conflict between our country and another where support begins to ebb (We're experiencing that now with the war in Iraq, incidently). The more protracted a conflict, the more pronounced our war weariness becomes. My question is this:
Do the warmongering races (Dregin, Korath) suffer "peace weariness"? Is morale dropping in my Korath game because I'm not rampaging across the galaxy, destroying anything that so much as looks at me? *Laughs* I am playing the Korath as Evil, so that may also have something to do with it.
The flip side of this question is this: Do the more peaceful races have "war weariness"? I've never gotten far enough with a relatively peaceful/Good race to find out.
Does anyone have any idea what I may be doing wrong (if at all)? Or, is this a side-effect of the Beta? Has anyone else noticed this inexplicable loss of support/Morale Loss? Any advice would be wonderful.
