Ive run into this in a few airports. This one is small aircraft only on Easy.
I was trying to get the achievement for 95% satisfaction. GA is over 95 as is passenger. but due to the consumable rating being so low its not possible.
I ran it for a while here and also when the values were at the minimum for consumables. I saved and reloaded a few times. but the highest i got it to was 45% and then it dropped again.
Anyone have any suggestions to try and fix it, or is it a bug?
