WARNING!!! DONOT ACCIDENTALY CROSS-CLASS ANYONE ELSE IN YOUR PARTY!!!!! If you do they cannot become jedi on Dantooine, the game will lockup everytime you try!
yep, dont do that, i remember the first time i knew about cross classing but didnt knew that i could turn my party members into jedi, so i was at Taris with Bastila and Canderous. Both were at level 7, so i FLu at Bastila's screen having Canderous next. I turned Canderous into a Soldier/Jedi Sentinel at Taris and was like WTF!!!!!! I got excited but it didnt lasted long cause he wasn't able to use FP or lightsabers, so i just loaded a previous save again.
