Pause bug: If you already have a defensive setup and overwrite an existing setup while in a multiplayer game, this will pause the game when you try to confirm overwriting it. This has only been tested in multiplayer, but is recreatable between different coaches.
Blitz Bug: I haven't tested this extensively, but it has happened to me once or twice, and I think it might be a bug. Currently, if you Blitz > Leap (failed) > Reroll > (Leap success), your blitz wears off, and you no longer have a blitz action for that turn. I think this happens with any Blitz interrupted by a reroll at the moment, but I'm not sure. Further testing needed.
