This was an issue first (and last) mentioned in the March 30, 2023 TWAB/TWID, but it has since disappeared from the Known Issues list and is still not working incorrectly. When reapplying any source of Restoration, your Restoration timer will revert to the base duration, regardless of remaining duration it had when you reapplied Restoration. This issue is ruining a lot of builds that use Ember of Empyrean, especially when combined with Sol Invictus or Phoenix Dive. I believe the correct behaviour should be similar to Devour functionality (or just simply don't allow the base duration to overwrite longer durations granted by Ember of Empyrean).
