Yeah, a known issue, a reason I started trying dagger/sword dual wield, gotta tell you I love it.
yeah it is a lot fun, my favorite style so far. i got the naked mod so my imperial girl goes around whoopin' ass naked, well besides boots and gauntlets, it is too funny. I had the two dagger thing going which was cool, but another issue, not sure if glitch, on those, is that daggers aren't adjusted by enchantments of wielding which i hava a good one, and the faster dual attack perk....
As for the other issue, i am doing fine with just using two reg sky forged steel swords and switching to heal occasionally.
