Each time I open the Shadow Steed's inventory, or open a corpse, I get another ring named "T" added to my inventory. I was also having a ring named "Ren Horse Ring" added, but it was fairly easy to track that down to RGO, which I plan to updated and start from a clean save after I resolve this issue.
For the life of me I can't find out where this other ring comes from. I've searched all over, and I'd use the formID finder, but the ring mesh appears to be gone. So if I drop the ring, it's invisible.
Has anybody else faced an issue like this?
