In the German event file event 40089 gives the choice of creating the leichte divisions, creating a single decent strength panzer or 4 very low strength panzers. Event 40090 allows that after poland or france is taken, the leichte divisions can be swapped out for panzers as was done historically. Perhaps if the second or third choice in 40089 is taken, 40090 should be slept. As is, the german can get 6,7,8,9 panzer thru 40089 option c and then get those same panzer divisions via event 40090. While it works, I don't think that's what you intended.
