the objective Achievement keep resetting to zero,
The invisible dead body, etc...
All these happened long time ago but never fixed. However , developed put the effort making new things, like pets, junks, making the storage explode.
The game save does not work .
And developer keep changing the rules, like adding deathclaws, mole rats, removing legenderies from wasteland. And now the new rooms are three tier initially, need more dwellers to upgrade. That makes the whole strategy changed. I have my vault surround with elevators and 2x rooms to avoid mole rats, now have to pull it down to fit 3x. I have down size the population to make the management easier, and now have to boost up again.
You must agree this game got strategy, even if I adjust to make it right, developer can change it anytime to make it wrong before I can complete my objective.
I have played this game for 7 months. It is a shame for a game with such good concept end up like this.
