It'd just be nice to see more of the breast expansion content in the cow content being used outside the one dungeon
like just a little more use of the cow/milk content with maybe some BE of the character equipped with the items or something

I'm betting they're working on something, but right now, the BE content is still relatively new, so they might get to it after a bit more of content is fixed and added (storyline, extra sidequests, fixing the questboard, fixing bugs, and more). So if they don't get to it, you can probably find something about it in later versions.

I deff second this, my biggest dissapointment besides the inability to retain the slimegirl tf is that the breast expansion content just drops off a cliff after the cow dungeon/outside the farm.
