Hi. I don't know how to post my mod list.
I haven't played in a while, but I came back this weekend to start over.
The icons worked fine, but a mod gave a bug to the black cat, so I restarted to remove said mod.
When I restarted, default spell icons were missing from the hotbar. Not the spell book.

I'm late for bed, so I'll check this and reply after dinner tom.

Edit: while I did add a few mods between those play throughs, none of them added spells. Also, my third attempt I removed two classes mods I don’t use, but the same missing icons were still gone. I’ve verified, but that added nothing.
