I'm trying to level the Daedric Summon skill on my stam sorc. I recently unlocked Bound Armor so I slotted it on my front bar to help level the skill line. However, since my back bar was fine as it was I left it off. Now, I realize that casting the spell then switching bars will remove the armor and I'm OK with that. But merely having the skill on one bar and not the other causes me to be dismounted when I swap bars. I've tried this with several other toggle spells and none of them seem to have this problem, it apparently is only a "feature" of Bound Armor.

Has anyone else run in to this "feature"? Or am I getting an extra dose of ZOS "special" treatment?
