Ah don't worry I just began a new game and kept the same team as before, this time with Growls ;)
The game is great man don't worry about it, keep up the good work it was great fun!
I really love this game and it's cooking mechanic and chill vibe, but sadly I got softlocked in the Natural Park area so I can't continue the game without resetting my save. I sent Growls into the box because I caught a new pokemon and wanted to level it up. Then the cutscene with Ursaring...
