@Boidster I was just anserwing his question. Neutral. Ofc they need money. They were at 12 million sold copies years ago. And now they are on 14 millions and they not only need to continue paying for the development of 7 days now, they also need money to develop their new game that they already work on. It´s understandable.
But not like that. It caused a lot of trouble for many people that could have been easily avoided with detailed information (before the update) about what needs to be done on the userside once the update releases. Ofc they can´t always communicate everything they do in advance, but if you mess up things that bad, at least a warning would be needed.
They also could have waited with this change until they can properly implement this i guess. I least i hope so, if this is such a mess because they implented this in a hurry due to badly needing money right now, that could be really bad for the game.
