Bugs and cheats listed below can be replicated on a device without the need of cheat tools.
Bug: When you play against Grizzlies of National Division II, if a player of Grizzlies is shown a yellow or red card, you'll see "Strickland #x (player's number) is shown a yellow/red card" instead of "Grizzlies #x is shown a yellow/red card" on the screen.
Bug: At the start of a new game, the coach introduces himself and says his name is Manly; however, the starting coach is always "Hartford L".
Cheat: More than one player can have the Captain skill at one time.
Hire a normal player (not a Friend Player)
Set the Captain skill for the hired player
End Game or Transfer Data
Start a new game
Set the Captain skill on a player
Hire the old player that had the Captain skill (make sure to hire after you set the skill on a new player).
Now both the old and new player should have the Captain skill! You can repeat this multiple times, with potentially everyone on your team having the Captain skill.
