Leaderboards reset is scheduled May 30
The date of the upcoming leaderboards reset have been revealed by CIS PUBG twitter account, the last reset has been performed on May 3 so this season is a bit shorter than we are used to. The leaderboards are scheduled to be reset on May 30 4 am CEST, so probably a short maintenance would be performed during this time as well.
The leaderboards will be reset at May 29 7PM PDT / May 30 4AM CEST/ May 30 11AM KST. The new leaderboard season start date and time will be announced soon. Any matches played after the reset until the start of the new season will be unranked.
It is not yet revealed when the next season would start so it would probably kick off at the start of the next month.
