Hi. I've unlocked almost all improvements of Chalice of opulence except Rune bonus 3. And when i finally got enough imperials for that last one perk, i've unlocked it and then realize that my progress is gone. Masterworks slot and Power and Efficiency 3 is locked again. So now i don't have enough imperials for this upgrades and probably i won't be able to earn them for the end of the season to get Moments of triumph seal. In the linked video you can see locked perks and this special mods for Power and Efficiency III in my inventory.
