A bug about The Coming Calamity Heroic Armour ! My armout and support gems disappeared!

I wore The Coming Calamity Heroic Armour and spent lots of time to choose the right support gems.
After I got through the portal, my body armour was missing.
I found that maybe it was the problem about the max number of skill gems, when I wore this amour, I got the 3 herald skills and totally had 14 skills.But maybe the number of skills can be 11 at most. When wore the armour, there was no hint about that. The bug happened when my character got through the portal to a map of tier 14, the armour and skills just disappeared! I can't find them in my stash tab or the ground of the map.
I want to get them back!

I restarted the game the armour was back but the other one disappeared and still got two support gems missed.....

The bug appears again, when I go into a map, my amour disappear.Now both of the armour come back, but all of the support gems for the unique armour's herald skills have disappeared. What's going on with the coming calamity heroic armour? This is very annoying. Please check out.
