It's cool how some of the default races comes with a few extra ability points for you to customize with. The Iconian Refuge, for example, comes with 6 extra points, while most of the others have 2-3. Unfortunately, if you spend these extra points sometimes the default abilities of the civilization you're customizing vanish.
For example:
If you use any of the remaining 3 points from the Drengin, their soldiering +25% bonus disappears.
If you use any of the remaining 3 points from the Yor Collective, their Loyalty +100% bonus disappears.
These are the two cases I noticed, but I'm sure there are more. It seems odd that this isn't documented, because at least in the case of the Yor, you lose a -major- civilization ability if you attempt to customize. I'd like to add that after I messed around with customizing the Yor, the Loyalty +100% bonus no longer shows up no matter what I do. I've tried the Reset button and the Clear button. This makes me very, very sad, as I was looking forward to playing the Yor =P
(Also, how does the AI deal with the remaining points?)
