There is only one last achievement that I need in Halo Wars: DE. It is the “back scratcher” achievement, in order to do that you must complete a mission on co-op with a friend, which is simple and all, until I guess this message, “Could not join that lobby, could not connect to host.” The game will not let me connect to my friend and vise-versa. We have narrowed the problem down to me, as in my friend can just hop straight into multiplayer or do a co-op campaign with somebody else. It’s not WIFI related, my WIFI is average, when it comes to gaming, as in very rarely do I lag to deal with lag or connection issues, or anything of that nature. I’ve tried restarting the console, uninstalling and re-installing the game and even deleting my locally saved data on my Xbox to try and get the game to sync up with the cloud. It may be the console or may be the game, I dunno, it seems to run everything else pretty well with no performance issues, but I got nothing. I don’t know what to do. Any and all help is appreciated and lemme know if you need more information in order to help me resolve this issue. Thanks.
