You got them today, but they have the quality as if you got them last season, that always happens on the first day. I think it's something like you got them after the usual daily maintenance, and then the season update took place, that's just my way of looking at it.
The best time to get them is after 4-5 days in the new season.....I've got my players just a few days from ending last season, so that sucks the same haha
