2-22-2019 Stamina Training Failure
We are currently investigating why this week's stamina training did not occur.
Update: The problem is identified. Stamina training did occur, but any skill updates that resulted were not displayed. The bug has been fixed, so everything will be back to normal next week. Inserting the training events for this week will be done on Monday.
If you wish to see if your player had a skill update, then you can check against the player's performance history. If the player played a match during this training week, their stamina value will be stored there so you can compare.
