Too many bugs for 5 stars
When Janus is supposed to take off an expedition expansion it actually removes a Development expansion and vice versa. When Janus is supposed to take off a military tower is actually removed a trading tower. Sometimes ( I am unable to precisely say what it occurs ) when you get a shovel it temporary appears, you are unable to select it and then it disappears. The Action Tile whith 1 shovel and 2 stars actually shows 1 shovel but only 1 star. And PLEASE add a goback button, too often you press something by mistake and the game is to be finished as you know you are then unable to get a good end result.
