Got an Embrace of the Relicbinder chest in the new season off of So’leah, in M+ Taz: Streets
It was 1/12 at drop.
AMR wouldn’t recognize it as valor-upgradeable, though it had the piece in inventory.
In-game, I upgraded it to 4/12 and sent a new inventory to AMR, still not recognized.
Took it out to ZM and converted it to tier; still 4/12, still not recognized as valor-upgradeable.
Snapshot is from just after the Creation Catalyst conversion to tier.
(I also have a 12/12 tier chest from the previous season that currently has the same iLevel as the 4/12 - otherwise identical except for enchant - tier chest. But the “not recognized as upgradeable” was happening all along since drop, so I doubt that other copy is relevant…)
