Custom games & campaign are broken...

Seriously getting tired of this. Halo 1 disconnects often, not lag which is odd, game breaking issues like player not able to move.
Not sure about Halo 2 co-op yet but Halo 3/4 seems to lag like crazy sometimes.

Meanwhile custom games are beyond broken to a point that loading custom games won’t even load, top of that it kicks the host, throws them back to halo start up.
…while Multiplayer is seemingly ok online from my own experience so far. 343i need to start fixing the campaign/custom games.
