Another driver from the loophole!

I believe there's a loophole in the Transfers market. Jack's 'level cap reduction' affected employed drivers stats to be capped to the manager level. This did not affect unemployed drivers. Unemployed drivers with the leaning tower of speed (all 19+ on the desirable attributes) from the old iGP were likely level 12 or 13. This level was transferred over and not converted to reflect a higher level and these drivers have a 1 in Composure and Knowledge.
With your high manager level, you were able to see powerful drivers who were likely almost all 20 in their attributes.
When you train these drivers to complete the progress bar just once, the system updates their level and they go flying up a few levels. My driver Ignacio Rodriguez was level 12 in the old iGP and the same in the new iGP. I noticed that in comparison to other level 12 drivers he was all 19 in every area except Composure and Knowledge. I decided to pick him up again and after training him he went up to level 16. I am a level 13 manager.
Once these drivers whose levels haven't been updated yet are hired and trained, the loophole will close itself on its own, or until Jack can apply a solution that updates these drivers levels.
