„Season End Reward Update & Cooldown Reduction Timing
The update to card cooldown times and related update to how season end loot chest rewards are calculated (originally announced in this post: @splinterlands/sps-staking-and-other-splinterlands-updates) is now planned to go into effect starting with the next ranked play season that starts on August 31st.

This means that the season end rewards will still be calculated based on the highest league achieved during the season for the current season, and starting at the end of the next season (ending on Sept 15th, 2021) it will change to be calculated based on your league when the season ends, regardless of what higher leagues you may have achieved during the course of the season.“
