This has been in the game for about 2 years, Nothing new.. now if you used your hearthstone in the past hour, your stuck untill the timer is up.. All i can say to blizzard is ?......? NOTHING!!

It's been broken for a few weeks - using unstuck would not affect your HS cooldown at all.

This is supposed to fix it so that it returns to intended behaviour - i.e. unstuck triggers your HS cooldown if off-cooldown, and resets it to 1hour if already on cooldown.
