Where is the ...
Fixed Host Migration. That little problem where you spend an hour doing some endless thing like Kuva Survival and then the host either loses connection or quits and your entire last hour is 100% wasted as you get nothing. (Also known as... we purchased a ton of servers to host on so that stopped happening.)
Fixed searching for a game. That other little problem where you try to join a party and instead of doing anything your system locks up and hangs at the finding party screen so you have to restart your Xbox at least 2-3 times a night.
Fixed not having an in-game market for all tradeable goods. Self-explanatory.
DE, it would be nice if you came up with fixes for these small problems before you try to expand content.
