Yeah, i've explain this on help chat after my crash, and they have say me click regulary on bag when i farm... i don't know that before, and after 4 hours yes.... big crash -_-
But, yes the game isn't the perfect, yes it's a beta, but if we can pay manything in real money, i found this normaly crashes like that are close with a random poke and not with just advice and sorry :/
Maybe you can't recovered data, but i've a sreeshot. Really, it's horrible, to have farm 4 hours for one crash. It's Feebas, not ratata T.T
