Bug in season changeover

In an MP league, after the season changeover, ball actions are changed and a lot of players have negative catch and shoot ratings with increasing numbers in other ball actions. I did import into PB19 our league PB18 file and after importing everything was ok. But when finishing the season, after the awards when ratings and financials are updated, the ball actions were changed with those negative numbers. As a consequence, the draft crashes and cannot advance (I was testing the draft class for the upcoming season).
