Player was a starter, I have made some substitution during the match but not related to that particular player and in previous games I have had the same issue even without making subs. During the live match I haven't changed my set piece takers or tactics.
I will take a look to corner kickers, if their assists are added or not, (I haven't scored on corner lately), to see if there is some sort of similar behavior. Now I have tried to change all the set piece takers to see if something changes
(Is it possible that piece takers are loaded at the begin of the game, so when a on free-kick goal is scored, the name of the player comes out correctly but there is a request for getting some info that fails before updating the rate of the player and his stats? )
I will let you know if I found some relation for this behavior or if changing piece takers works.
