Whilst questing, I get to the Hasrah Ancient ruins, and there are a lot of uneven floors in there is the first example I can think of. These spots are found quite often, especially if you are fighting in a combo, and are hard stopped by a slight deviation in ground. 

There are also quite a few auto paths that can be stopped by slight changes in elevation, for instance in the calpheon shrine quests, like autopathing to the boss basically it stops at the end of each row of stairs which can be very annoying. Autopathing hang ups in general can be very frustrating, for instance you get up to eat come back and your player hasn't traveled like you had hoped. Especially when it is a new area and that isn't something that is fixed, it can be very frustrating, and we wonder about the quality assurance team if they can't get something like that correct. Basic pathing through quests shouldn't be a point of frustration for a player new or otherwise. 

Thanks for the consideration and or discussion. I can try to start logging if that is needed.

good luck 

when you are too fast moving down, you fall which stops sprints, horses and skills. Was here since the start, probably cant fix since its physics.
