i didn't found anything about this problem.
After some season some ahl teams have only 13 players and can't even suit up a full line up.
TBL Rosters v8.2
EHM early access 1.2.1
size of database: normal
NHL, AHL, ECHL, OHL, WHL, QMJHL and Memorial Cup are enhanced.
Many teams with this problem: Manitoba Moose, Providence Bruins, Bridgeport Sound Tigers, Hartford Wolf Pack, Hershey Bears, Wilkes-Barre/Scranton Penguins, Toronto Marlies, Binghamton Senators, Utica Comets, Rochester Americans, Albany Devils, Grand Rapids Griffins, Rockford IceHogs, Chicago Wolves, San Antonio Rampage, San Jose Barracuda, Ontario Reign and Bakersfield Condors.
In all those teams is at least one player too less.
It happens always after one season. The screenshot is from the offseason, but this problem is also while the season. I just managed one team, the Sarnia Stings from the OHL.
I started also a new game with full database and there i had also the problem.
I uploaded a save game, "WookieCrasher_not enough AHL Players in CPU Teams"
And i uploaded also the same screenshot like i attached here " WookieCrasher_not enough AHL Players in CPU Teams_1"
