C's E. Armory unequips all gear. . .fourth weapon set not added back.

Citzal's Enchanted Armoury seems to, by design, unequip all gear. Considering how nice my gear is, this renders the spell pretty useless, but that isn't what this post is about.

If you have an item that adds a weapon or item slot, and you have something in that slot, whatever was there is removed and not put back when the the spell expires.

If you had a weapon, for instance, in the fourth slot, then that weapon is put into your stash.
