duelist tree

i was wundering about the duelist tree that ive had since forever and today i decide to use it after about 10 mins i remember y i stoped using it and that was because theduel pistol dash, and another ability didnt work, i wus told that it was because of a bug and that i needed a second single gun, i grabed me a lancet and tryed again, still didnt work maybe i need to restart? i was wundering if there was sumthing i was missing

another thing i was wundering is that soe got rid of the level exploit in a snap but they havent fixed this bug for about 4 months? maybe more:\ ne way....
