It looks like the new Demonic Healthstone (224464) isn't available when created by a warlock. The regular ones do appear in the Health button.

Thanks for the great addon!

Is this not a thing? I swear my healthstones show up in classic under the health potions button.

Not sure, I started playing Warlock and maybe it's just for the newer Demonic Healthstone that was added in War Within? But I also haven't noticed regular Healthstones in there. I'll double check those when I grab one again.

Edit: It does look like regular healthstones are there just not the demonic ones so I updated the title and issue.

This should be fixed in the latest version (11.0.2.03)
