I'm on PS4. I can't get beyond the hidden blade training. I complete the banquet in the hall and talk to every one, including the King. I received the hidden blade from Sigurd and follow him to the training arena. Balim starts guiding me on how to use the blade and the little green indicator above the dummies heads appear. I take out all the dummies in order but then after I have assassinated each of them......nothing. The three characters all remain silent and just stand there. I'm just stuck going round in a loop. Can't play on any further so have quit the game out of frustration for now. I just hope the devs fix this and restore my faith.

Having had this issue I tried simply restarting the prodigal son quest by logging on at the very first save of this quest, using the load screen in the menu. I simply followed Sigurd to the banquet hall. Now this is where I noticed a difference from before. When I talked to everyone previously, Hytham was not available for me to talk to on his own. This time he was stood alone and eager to have a cosy chat. Following this I accepted the blade from Sigurd and followed him to the training arena. Unlike before, all three of them stood apart from each other and followed me as I assassinated the dummies. The quest ended and I followed Sigurd to the boat. Hope this may help others who are stuck.
No further hitches as yet though from what I'm reading there seem a high number of bugs in other quests that make you wonder what amount of testing was done prior to release.
