Expected Results: Soothing Mist spell is a channeled spell that allows for the use of Enveloping Mist and Vivify to be cast while channeling Soothing Mist. Soothing mist should not stop the channeled cast while casting the other spells.

Actual Results: If you mouse over a party member and start to cast Soothing Mist the cast gets broken when you try to cast Vivify.

Steps

1. Target player unitframe and cast Soothing Mist
2. While channeling Soothing Mist cast Enveloping Mist.
3. Observe that soothing mist continues to cast while Enveloping mist is cast.
4. Target party frame (default UI and Elv UI both tested) and cast Soothing Mist.
5. While channeling Soothing Mist cast Enveloping Mist.
6. Observe that soothing mist STOPS casting to cast Enveloping mist.

Thanks for the detailed report!

I'm not able to reproduce this on my Monk though, how are your bindings set up? I'm testing it with this configuration for both SM and EM:

(also tried it with the Mouseover Target unit)

Enabling the "interrupt current cast" toggle on EM does cause it to stop casting SM, but that shouldn't change the behavior between player frame and party frames. Could you post the contents of /cc dump as well? That will include information on the macro it generates.

This is odd. It worked for a little bit then I flipped a check box on and off for interupt and now its not working again.

Ah, can you try setting the targets for EM to "Mouseover target" or "Unit frame"? The "Default" target is similar to the behavior when clicking abilities on your action bar, it targets the current target or yourself if you don't have a target. So in this case you will stop casting SM because you start casting EM on yourself.

I did notice some instances where things weren't properly update after making changes, I'll definitely look into fixing that.

That was it. Thanks for that tip. I am glad it's not a bug.

Thanks for the addon and please let me know if there is anything I can help test.

Awesome. glad to get it resolved so quickly, and thanks for the super detailed report/info!
