[Aether Keep] My Tier and Lift from the previous season in Aether Raids hasn't carried over to the next season.

Normal seasons (Light, Dark, Astra, and Anima) and Chaos season have separate Lifts and Tiers. Due to this, Lift and Tier in Aether Raids is carried over in the following way. 

• If the previous season was a normal season, the Lift and Tier are carried over to the following normal season.
• If the previous season was a Chaos season, the Lift and Tier are carried over to the following Chaos season.

Please keep in mind that Lift and Tier are not carried over from a normal season to a Chaos season, or from a Chaos season to a normal season.
