I LOVE the game itself. Amazing play through and lots of solo things to do when your friends aren't on.
But the lag is ridiculous. When I first got the game I literally walked away for an hour to give it time to figure its self out
Just this morning me and my friend were trying to get a diamond gnome from the water ruins (plant side), and he ended up having to quit because he was so mad. He couldn't make a single jump for the second half of the run-through glitching mid-air and practically diving straight into the water. It was absolutely ridiculous.
And after he left the lag seemed to transfer to me because I failed every second jump after that.
