Right soooo 4.5 did come and go... And the retroactive fix seems to have been pushed back -_-
Patch notes:
Fixed an issue where Smugglers and Bounty Hunters were not getting credit for completing Act 3 if certain conversation choices were made during the final Missions. This fix does not apply retroactively. If you have already completed Act 3 on your Smuggler/Bounty Hunter, you will be credited with Game Update 4.6.
Sadly enough that mean waiting another month before we get anything and it only say Smuggler/BH nothing about the knight.
