It seems to be working perfectly a lot better haven’t crashed at all! Tho I have seen teammates be crashing (other platforms) but not as much luckily thanks Strawhat!
Xbox Series X EU user here.
I’m very happy to report that I haven’t lagged out (Error 2014) or crashed once over the weekend while playing several Havoc 40s, Auric Maelstroms, event missions and several normal missions since the update!
Whatever you did @FatsharkStrawHat it seems to work. Keep it up!
