Hearthstone not working but goes on cd after use

I use my heartstone and it doesnt send me anywhere and my hearthstone goes on cd. been happening for days now

Same thing has happened to me twice so far, each time on a different character.

First was my Hunter in Undermine. I cycled through all of my Hearthstones, tried the teleporter, tried the rocket transport to Ringing Deeps, and nothing worked.

Second happened shortly before the writing of this very post on my Druid in Hallowfall. Hearthstone on CD, no port, so I decided to just manually fly back up the tunnel. But I couldn’t, because I hit an invisible wall about half way up the broken Coreway lift.

I’m tired of these bugs, boss.

Edit: It broke on my Hunter again.
Hearthstone, no NPCs or players in Dornogal, zoning out and in does nothing.
Great game, blizzard, high quality.
