@driftspace: what consoles did you play previous ACs on? I've played them all, extensively, and Unity is the first one this bad. Others had issues here and there but not like this. This is Bethesda equality hijinks
I have not played "Unity," so I have no basis for comparison regarding this particular issue/game, and I won't assert that all five of the aforementioned games had game-breaking issues; I think maybe 2-out-of-5 did. I enjoyed them for the most part, regardless of bugs, until the basic chore-list-with-annotated-map style of game-play (and jumping in directions I did not intend) started to wear on me. I really enjoy how the series spins historical events, but I just can't play them anymore. It's too bad, because AC multiplayer was really starting to become pretty awesome when I quit...
You know what I am saying with the Bethesda comment; AC (for me at least) became one of those franchises where I just refused to play them until several months had passed. Even when I purchased an AC collector's edition: I would shelve it for a while, let everybody else beta-test it, and wait for patches.
