Alright right now I just noticed this. the below is a link defining. I was playing around with my Custom Civ, and for some odd reason when I reloaded a earlier save of my Civ, it added on to it... I think thats the word cuz my ABILITIES were well... increased. and could still play the game even though I had some items in the red. For clearities... When I "loaded" my saved civ, the current civ was altered, but it seems that Abilities just got added on instead of completely changed...
