None taken, and no this isn't a fluff mod, we will always offer support.

This appears to be a conflict or LO issue. The spells being called are not from Darkness Hollows. According to Google they are from Duke Patrick's Combat Magic II but I don't see that in your LO. Have you recently uninstalled that mod?
Actually I just installed it along with Silvercliff about the same time or concurrently with DH but haven't played it yet (which is why it never came to my mind and I reflexively blamed DH—apologies again.)
It didn't show in the load order because BOSS didn't know what to do with it and dropped it at the end. The LO I included was actually the Bash Patch because it was the easiest to cut and paste, and, of course they didn't show up.
I usually don't install more than one new mod at a time and this is a good reason to go back to that practice. I will play around with it and see what happens and let you know. (Later today... It's getting late and I'm fading.
Thanks again for the detective work. i never thought Google would return something like that.
