Master Chief Collection PatchA new patch was planned to roll out for the Master Chief Collection last week but it has since been delayed. The patch had been mentioned to include some fixes to matchmaking whilst adding some general tweaks to multiplayer, campaigns and interfaces.

Whilst 343 Industries failed to mention why the patch was delayed, they have since confirmed that the release of the patch has been pushed back till later this January. According to 343, the patch should be up and ready to install within the "next few days."

It's a shame that after all this time, the Master chief Collection is still not working 100% as planned, but 343 are still working on it.

The patch notes for the upcoming patch rolling out later this week can be read below.

Improved matchmaking search success rates.
Made an update to reduce instances of "Awaiting Privileges" matchmaking errors.
Made an update to ensure player counts more reliably match the expected numbers for each playlist.
Fixed an issue where player would sometimes appear to be searching in an incorrect "FIND GAME" screen.
Added countdown sound effect to the voting timer

General multiplayer:
Made several improvements to party joining through the in-game Roster.
Made an update to ensure that the mute icon is visible while in Matchmaking.
Fixed an issue in Halo 4 where players could equip the same weapon as their primary and secondary weapons.
