This game has been extremely unstable (amongst other in-game issues) since the most recent mass update (2.14)… Ludia, you need to fix and stabilize this game asap and do it well before adding anymore creatures or unnecessary features or additions. If you can’t provide a stable game for your customer base, then you will eventually lose said customer base… fix it!
