Coming Calamity bug

Hello,

I've got the coming calamity unique armor with the 3 heralds, when i socket all 4 supports gems on herald of ice and ashes that work fine

If I socket 3 supports gems on herald of thunder that work, but if I sock the 4th on it and I change area, the armor totally disappears of my inventory .



If I log off and log on, the armor reappear but the 4th support gem I've added have disappeared...


Can you explain to me why ? It's a bug or I don't understand something ?

Best regards

No issues with the 2 mentioned Heralds, but when you put in any support gems into Herald of Ash, the Armor will disappear when returning from a map.
