We've been receiving reports that Wisp Lantern has been causing performance issues, especially when there's more than one on the table. We've removed the most "intense" VFX assets from the Lantern and will be monitoring if this is enough to help performance.
Additionally, Echoes Mode Opponents should obtain Evolving Relics in much more natural timings. Evolving Relics have a habit of placing themselves at the end of storing arrays, so it may not be perfect, but should improve the Echoes Opponent Relic acquisition flow.
