On third round as well, checked achievement again to verify which ones should be available, all of the chests that should have been available were not...I ended up checking all of the chests twice, NONE were available, all showed already open. Went to Herathi 3rd time to get screenshot for in-game report showing the open chest in the middle and the hero screen with the master diver achievement open to show Herathi chest had not been opened this round. I have been having issue intermittently but was always able to find one that would open until today. (I did try visiting the LA npc before 2nd round, made no difference.)
