I stumbled upon this little cheat (yes a cheat) that convieniently fixes your stances (if you do it this way)
I was looking through single_1.sab and saw
I wondered for a min. and played sp
I then tried a cheat i thought existed since JO
here it is: setsaberstyle
ok now heres the way to fix your stances
1st: bind a key to setsaberstyle SS_DUAL
e.g. bind n saberstyle SS_DUAL
2nd: Bind a key to Setforceall 3
3rd and finnaly: go to tavion stance and laugh at it and press n or whatever key you binded setsaberstyle SS_DUAL to
then, press your setforceall 3 key and you go to staff stance!
then you can cycle all through it again...
too complicated? oh well, it works for me
