This is the tragedy of Ubisoft. Their modelling of cities is phenomenal, they just don't waste too much energy on the "game" part.
As far as glitches go, The Division is a goldmine. I’ve encountered as many ridiculous problems here as I did with Assassin’s Creed Unity, including the classic case of falling through the floor and getting caught in an empty void underneath. This has happened multiple times, to the point where I’ve even had to abandon co-op play because of it.
