COMING CALAMITY JUST DISAPPEARED

Upon socketing my 18th level Herald of Ash skill's (provided by the body armor Coming Calamity) 4th support gem with Hayoxi's Fulmination, the Coming Calamity Armor suddenly disappeared!

After relogging, the armor was back with all socketed support gems EXCEPT the Hayoxi's Fulmination!

This is very nasty bug that seems to exist for more than 9 months already and is not properly addressed! I just learned about this after googling my problem.

On top of that I lost a rare Lineage support gem, which I just got from my last temple run.

Please, fix the game and if possible return me the lost support gem!
