Yeah this is bad enough, but I haven't worked out yet if the regens are only taking the UIDs of players that have retired without history retention or not. And if not, how does that impact, say, Manuel Neuer when he retires and a regen gets his ID? How does the game keep his stats/history and will the regen have elements of the old player in their bio?
Someone has reported a bug whereby one of their regens declared for a NT that isn't in their nationalities, is it possible the regen declared for a nation that belonged to the previous player that had the UID? Idk, but it all sounds borked to me...
