Something seems to corrupted two weapon style fighting. Pattern that repeats is that my character uses off hand weapon for primary attack i.e. of four attacks at least three will be with off hand, usually only first is with the main. Primary suspects are Tobex, maybe fixpack or Item revisions "Dual Wielding Changes for Light and Heavy Weapons". Need more testing though since I for now use weapons my PC is not proficient with ( still waiting to find good katana ).
