Hello I saw you reply to someone about the visitors problem, I have encountered the same problem, when they were 39/40 upgraded they were fine doing 37/82. When I maxxed them to 40/40 outside of games the card shows 37/84. But when dropped in a game if you highlight the card they show 30/73 stats which I think is their base level 4 stats. It's not a visual bug they did not kill a new kid with 63 hp when they each shot him. This happened to me today may 22 as I got them max https://imgur.com/a/SogofUp
