Is Building Buildings on the Sea Floor Impossible?

I can't think of anything else to do to it. Is it simply impossible? If so, could Uber perhaps look into fixing it in the near future please?

mines are buildable on the floor
can't you work with that?

Are they? That'd be odd.

And judging by the json it's actually a bug.

afaik it was possible till the last major patches it was to prevent doxraiding between islands

There's nothing in the json that would cause that, it seems like a bug to me.

Why? we cant even see anything under the water, while it was awesome in TA, will need to change the visuals around for PA

No underwater bases ; (

That's an airfactory on the seafloor
But why is this thread in general?

Is there anything that is amphibious anymore? Seems like a great niche to fill. I also miss underwater buildings from TA.

dox, slammers and combatfabbers are amphibius
and while not underwater a fair ammount of structures can be build on water

I couldn't get drox to path into the water no matter how hard I tried. Are you sure?

unless it has been changed without my knowledge it should be possible
