The Coming Calamity Heroic Armour and support gems disappear when Socket Amanamu’s Gaze

After equipping Amanamu’s Gaze together with The Coming Calamity Heroic Armour, nothing happened at first. However, after warping to another area/loading a new map, once the map finished loading, The Coming Calamity was gone, and all support gems linked to the Herald skill disappeared.

I then restarted the game. After logging back in, the armour reappeared in my inventory instead of being equipped, and all support gems linked to the Herald skill were completely gone.

I purchased new support gems and socketed them again, then restarted the game once more. This time, the armour remained equipped. However, one support gem (Embitter) linked to Herald of Thunder disappeared.

I bought the Embitter gem again and restarted the game multiple times, but the same issue keeps happening — Embitter continues to disappear.

I also tried removing Amanamu’s Gaze from The Coming Calamity and then restarted the game. After logging back in, Amanamu’s Gaze still in The Coming Calamity Heroic Armour's socket.

At this point, I am afraid to continue playing and have not tested warping to other areas, as I am concerned that The Coming Calamity may disappear again along with more gems.

I have stopped playing the game for now and will likely wait until this issue is fixed.

Update:

After further testing, I believe I may have identified the possible cause of this issue.

The problem only occurs when The Coming Calamity is corrupted or twice corrupted. In these cases, the issues (body armour, Herald skill and support gems disappearing) can occur with any socket gem in that armour.

When The Coming Calamity is not corrupted or twice corrupted, the problem does not occur even i socket with Amanamu’s Gaze or any socket gems.

Hopefully this information helps with investigating the bug.
