It's my understanding that the bug is constant. That said, 2-handers are not *entirely* useless even though they're horribly bugged. They won't work at all against cavalry (check it out sometime -- they just stand around and let themselves get whacked in melee), but they do work *sort* of in melee against infantry units I believe. I had fairly good luck as Russia charging my Woodsmen into rebel Spear Militia. My woodsmen chopped up the spears and sent them running--but when the rebel HAs entered the scrum, my woodsmen died FAST.

Can anyone else confirm/deny the efficacy of bugged 2-h units vs infantry?
