Fire Emblem Heroes: new Tactics Drills map, issue with Aether Raids after the recent update

A new Tactics Drills map has been added to Fire Emblem Heroes. “Test the Ruler of Flame” can be found in the Grandmaster section; beating it gets you one orb.

Also, an issue with Aether Raids has been discovered following the 3.5.0 update. Here’s how the in-game notice describes it:

When entering a Rematch battle from Aether Raids – Defense Results, your opponent may be treated as Tier 1 with a Level 1 Fortress (D) and a defensive team made up of 4 Heroes. (The opponent’s actual Tier does not change). As this happens, players in higher Tiers have an especially higher risk of losing defensive battles due to this larger Tier gap.

Intelligent Systems is currently working on a fix for this. As a temporary workaround, if you want to make sure that your Mythic Heroes appear on your defensive team, you should put them in the first four slots of your team.
