So I set up a Utility Macro for my Warlock on Classic. To create healthstone and use with button 1 and button 2. Mod:Shift would make Soulstone and use Soulstone. Mod:Alt Would cast Summoning and Ritual of Souls. It was working last night when I made it, but its not working today. I disabled all my plugins, still didnt work. Made sure to check if self cast was using Shift as hotkey, it wasnt. I disabled all of my Shift+Keybind’s and that didnt work. What could it be 
I dont know how to send Imgur links as hyper links but the Macro is:
#showtooltip
/use [nomod,button:1]Healthstone
/cast [nomod,button:2]Create Healthstone
/use [mod:shift,button:1]Soulstone
/cast [mod:shift,button:2]Create Soulstone
/cast [mod:alt,button:1]Ritual of Souls
/cast [mod:alt,button:2]Ritual of Summoning
Probably just need to delete and remake it, happens sometimes. I’ve done some basic optimization.
#showtooltip
/use [mod:shift,btn:2] Create Soulstone;[mod:shift] Soulstone; [mod:alt,btn:2] Ritual of Summoning; [mod:alt] Ritual of Souls; [btn:2] Create Healthstone; [known:386689] item:224464; item:5512
I have tried deleting it and remaking. Ive tried using /cast instead of /use. I tried using your optimization and its not working either.
Which part isn’t working, just Soulstone?
Well the healthstone wasnt working for a second, but i grabbed the same macro again and put it in the hotbar and then it did work. So yeah it seems to only be casting soulstone (not using). If i put the macro to my hotbar with the keybind Shift+1, and presumably any other one. It does work. But I have disabled all of my Shift+keybinds to see if that was effecting it. And it wasn’t. Note, It does switch the tooltip to soulstone when I hold shift. And it does create one with button 1.
Edit: I guess after a while the Use healthstone stops working too.
Edit 2: So when I got on today the macro isnt working at all. My other macros are. What could be causing the macro to completely lose all function?
