I was thinking this didn't need clarification, but maybe it does.  The two places I looked for Empowered Banshee and didn't find it is in the "on spell cast" trigger and the "give aspect" action.

I just had it apply a buff to eternal on spawn, and summoned it the normal way, and it worked fine, so it maybe only happens when spawning with a trigger.

Yes, "import" "workshop maps" in the editor.

This says resolved, but I tried opening a map I uploaded to the steam workshop, and all faction settings were reset in that.  In addition, it removed the description and other map info text.  I don't know what else it might have messed up because I closed it again and went back to editing the pre-publish version of the map.

Opening maps published to steam in the workshop is most definitely still broken!

apparently it doesn't let me edit, so you're stuck with my run-on sentences.

Uh, I select a script to trigger off of a spell, click the magic picker, and empowered banshee spell is not present.  How obvious does this have to be?  Is this not as plain as day?  Surely, you must be joking, asking for clarification on this...
