Regarding the bug in FC25 Classic Match

If you transfer a player using "Club Transfers" and then quit the game, restart the game, select the team that you transferred the player to, and try to play "Classic Match," the game will crash.

We would like to be able to play offline "Classic Matches" with original teams created using Club Transfers, but this bug makes it impossible to do so.

This is probably a bug in the game, so there is no solution. I hope the developers can fix it as soon as possible.
