I have two Dragon Maces, when I add them both to my favorites one keeps removing itself from my favorites, it won't let two of the same weapon be in the favorites, anywhere, this is extremely inconvenient since I dual wield maces because I love the ignore 75% of armor perk, any way to fix this bug?

Can you hit the same hotkey twice?

Just use 2 separate keys. I don't think if you have two of the same type of weapons, it supposed to allow you to pull them out at the same time, it just does that, because they are stacked. !!!
