Yes, we do test the game before releasing any new version of it, but as you might have noticed, the game is quite big and some issues may escape from the vigilance of our small team. Though, we are doing our best to resolve as fast as we can any problem any of you can encounter.
As most of you are really great people, we appreciate when you make our job easier by giving details of what seems to not work so we can spot and fix that faster and more efficiently.
