POE 2 - My "The Coming Calamity" armor just disappeared

My Gemling just lost his! WTF!!!!!

This bug is still happening. Lost 3 expensive runes because of it.

Bump, heard the exact same problem haven’t been able to put it on myself yet but I am scared to try.

This bug stil l exists. I think soul cores or 3 socket ones are triggering it. May be also caused by some kind of support gem.
Here is proof:

Sadly, I lost dialla's support this way.. Eh..

Hi guys,

I had the same problem a few mins ago. I was playing with Herald support gems and I think I put Brutality III on 4th gem slot in Herald of Ash. After min or so The Coming Calamity amour disappeared. What a pity it was 3 sockets 40 AR... :")

Update: After exit the game and login again amour is back but Brutality III gem is gone. So it seems this was trigger in my case...

Same thing happened to me (playing a deadeye not a gemling). I logged out and logged back in and the chest piece came back and all my soul cores are still in it; however, I did lose all the support gems in Herald of Ash. Most stressful few minutes thinking I had somehow deleted it off my body while adjusting the passive tree in my hide out. Mine seems to have disappeared after socketing in "fire mastery".

Yeah.... This is still happening. Just lost it and nearly had an effing hart attack, cause I literally just traded for it a map before.

I added nothing, but 2 extra support gems, but they had Spirit cost. I stuck Cannibalism and Precision in the additional slots I just got into the Herald of Ash...and Pooof!!! Armor was gone. Reloggin brought back the armor and all the heralds, save Herald of Ash had all of their gems still in. Herald of Ash is the only one that returned completely empty.... so, the bug doesnt require just special gems to trigger.

The supports I stuck in, both had additional spirit costs... I am trying one of them at a time... will see if it happens again
