There are numerous boundary-box issues(re: object collision) with a majority of in-game assets where an object's appearance doesn't match the physical space occupied (re: many fences/bridges/walls in the world).

Similarly, there are a ridiculous ammount of invisible walls that seemingly exist for no reason whatsoever except to inconvenience players (re: being unable to jump off of the gate wall in Aleport) in nearly every zone in the game while being absent from others. There seems to be very little rhyme or reason to what is pass-through and what isn't.

Many objects/issues seem to be leftovers from 1.0 & never had their collision fixed, as well as many housing objects not being standardized (re: some object placement within Lavender Beds function differently than in Mist).

A future fix for consistency sake would be nice.
