The time is June 2034, which is a world cup year. I am managing Belgium and was playing two international friendlies before the start of the world cup. I was playing players that are lacking match sharpness in the two friendlies to help them gain sharpness and prepare for the upcoming world cup matches. However, after the first match (Mali) was played, all the players that played did not actually gain any match sharpness at all. But their condition (stamina) did changed, and said they were tired from the last match. So I played one of the player (Daan Dierckx) again in the next match (Qatar), after the match he still didn't gain any match sharpness at all. The rest of the team again did not gain any sharpness as well.
I found this bug disturbing, although it was not that big of a deal. But still defeating my purpose of letting my players get ready for the world cup. I would also attach two screenshots to show what I mean. Hopes this get fixed in fm23.
