Heya!
No worries! And it's been an incremental thing; stuff like the different collision during walking and standing is slightly better than before, Atro City has more tall buildings, and characters also stop colliding with smaller buildings faster than before.
So there isn't going to change to much still on those fronts, realistically, I think; in terms of gameplay it feels acceptable to me—although balancing for the new city is going to change still.
Also there is a cheat to disable all character-building collision: I'm out of town at the moment, but iirc it's "dontstopmenow"
