Falkor the Luck Dragon

I am also having this same issue. Any time I attempt to change any of the training sessions, they disappear. If I change the session on the week I am on, then I cannot get them back, but if I make the changes on future weeks, then I can change the preset to get the sessions backs. This has been ongoing for weeks in my game. I uploaded the save, it is called: Squaks Bodawks - Unemployed.fm
