Last week’s patch introduced a bug that unintentionally caused people who played Battlegrounds immediately after the patch to have their rating reset. We quickly squashed that bug so that no more players would have their ratings reset in this way, and, at the same time reset the affected players’ rating to what it was just before 21.4.
Unfortunately, this introduced another bug that caused them to gain more rating than intended for each game following the initial fix.
Tomorrow, we will be implementing a fix that will stop players from gaining this unintended bonus rating. For the top 10% of players who benefitted from this bug, we will also be reducing their ratings to adjust for those unintended extra gains.
We will update this post once that change has gone live.
Update: This patch has now gone live in all regions.
Update 2: Since the patch went live, the team has been correcting a small number of additional player ratings that were not caught in the initial sweep. Nearly all corrections have been completed, but the team is still working to correct a very small number of players that have not yet been corrected.
Update 3: The individual corrections have been completed. The team will continue to keep an eye out for any potential anomalies, but at this point the issue is believed to be resolved.
