I came here looking to see if anyone had the same issue. I found a few people described the same issue that i just got, but they were notified the issue was resolved 12 hours ago. I just received the message saying my lootboxes from last season were opened ( i did not have any) and one of my legendary was taken.
I’ve also not seen anyone say anything about competitive reward progress. i am receiving 10 points per win but the progress bar still says maxed from last season.
