But...you are not reading or understanding the issue.
When starting a BAP career with doing the Memorial Cup so does the save start before the end of the 24/25 season. The database therefor seem to skip the fact that Marner was not given a new contract but was instead traded to Vegas and given a contract. Now that I started a new save just yesterday so did he still stay in the Leafs team when pre season came around. So something is wrong there or is that how it is supposed to be? And I dont have any other roster downloaded except the one you mentioned, so I cant use any other. So there has to be something with how BAP handles the roster or just that player specifically. So it would be nice if you looked into this if this is a bug or explain why he is not moved to the Golden Knights. And just to be precise, this is ONLY in Be A Pro, not in playing a quick game or franchise mode from what I can tell.
