We have the same issues where at least 2 of us try playing together on the same wifi and get the same results with freezing, super lag, and crashing/dashboarding at random. No matter who host the shared world the host will freeze randomly of and on. Then today after the patch if I try sorting the chest now it just dashboards the whole game. I have played this game since the beginning and love it but these crash bugs make it difficult to enjoy.
