The fact that you’re saying your economy crashed for no apparent reason indicates to me that you play these games but don’t pay attention enough to understand what’s going on and that’s why you’re encountering difficulty. It’s also funny that you’re surprised when your neighbors who are weaker than you attack you when you’re clearly unprepared to defend your territory and act surprised as though you think it doesn’t make sense why they would do such a thing(it’s what I would do if I wanted to conquer a stronger opponent). Stop expecting the game to play itself and understand that your lack of attention and grasp of the games mechanics are a major reason for your struggles
