After the update, pilot training has become very slow... With the pilot at 100% if you train him in one category he only improves +1... Compared to before which were 4-5 points
In my opinion it's a bug in the game... Because if you select only the physical he develops the +1 or in weight and in resistance if instead you put in the "all" item and train him with the +10 he gives you 4-5 points divided by mental, driving ability, physical items!
