I've seen how rampant this issue is on both ps4 and x1 and wondering why Ubisoft refuses to address it? I just spent hours trying to get all the skills (none that you really need throughout the entirety of the game) that I now have nothing to show for. If Ubisoft doesn't support their own games why should we? All I'm saying is- if you're going to put achievements in the game- just make sure they work.
