The Halo Championship Series, the official eSports league dedicated exclusively to the popular sci-fi shooter franchise, has been postponed due to ongoing matchmaking issues with Halo: The Master Chief Collection, developer 343 Industries has announced.

“We know that Halo fans around the world are excited for the launch of the Halo Championship Series, and we are too,” 343 said in a post Halo’s official website. “The first pre-season online cup was originally scheduled for 11.16, however, we’ve decided to postpone until the following week, as 343 Industries is focused on resolving existing matchmaking issues. This delay will ensure that the first pre-season cup is up to the standards of our fans and competitors.”

343 said that it’s now targeting November 23 for the pre-season cup. It will provide updates via HaloWaypoint.com/HCS and ESL.gg/HaloeSports should that change.

Late last night, 343 also released a content updated that addresses campaign, UI, and some Matchmaking and party issues. A larger Matchmaking performance-focused update is currently planned for release next week.

As written by 343, here’s what’s included in the most recent update:

• Fixed a variety of issues that caused players within the same Matchmaking party to be placed on different teams. In rare cases, this issue may still occur, and we are investigating additional fixes.
• Fixed a Matchmaking issue with behind the scenes team skill matching, allowing team skill matching to be more accurate in both ranked and unranked playlists.
• Fixed an issue where the campaign HUD did not reset from level to level with scoring or time HUD enabled. This will clear out the full visualization of level segments, which was previously not reset.
• Fixed a variety of issues with campaign leaderboards and scoring HUD, so now when scores are posted, score, kills, time, deaths, and penalties will be reported correctly for new mission leaderboard entries. We are still working on additional fixes for playlist leaderboard entries.
• Fixed an issue with competitive HUD time split. Now, when players have competitive time HUDs on with a rival set, they will see per-segment split times for whether they are ahead or behind at each segment.
