My suggestion is related to what happened during this last update, several players were directly affected and all they wanted was to play the game.
I know that the Atelier801 team is smaller, but that is no excuse for being so disorganized in relation to the update system used in the game.
So through this topic I suggest the creation of a test server that is not directly connected to the official server, where player data is not saved in the database, making it easier for the team to release updates within a closed environment where they could ask for some players test new features before the official release within a short period of time so that they report errors, bugs and problems to be fixed before the update.
It would also be great if the test server was only open during a phase of testing new features so as not to get worse in terms of economy.

We have suggested that to Tig and Meli already, we doubt this is going to be done, but let's hope. It's a shame that changes are deployed to the game without a basic test.
