Looking at the data, and you players have been set as you said (Kliem, Stanway, Dempsey, Pohlmann and Innes). That isn't even your default lineup (maybe it was but you changed it in the meantime?) so I presume you had to have set such a lineup at one point. Maybe your further changes in the lineup did not stick because of the database problems but I doubt it.
I admit the problems with the database yesterday affected a lot of things and we are very sorry about that. However, please reduce the chance of such problems affecting you by setting the lineup sooner and setting a default lineup.
I hope we will sort the problems soon enough.
