Tested and confirmed - the Squad Stats and Skills screen CM column shows all squad appearances, not all qualifying on-pitch appearances.
Palace Casuals before tonights match:
The 'Match Ended' screen showing the ratings of those players who actually got onto the pitch - I would expect that all these players except M. Kozak (who played less than 20 minutes and therefore does not qualify for an appearance/rating) would have 1 added to their CM column.
Not so - MP column has been correctly updated, but all the players listed as GK-ST starting positions and S1-S7 have had 1 added to their CM appearances.
Will be posting this in 'Bugs' Forum...
