Mysterious and buggy lake appearance in high-wealth residential zone

[EarnestErnest 4]

Greetings

So I just started building in my second map, being this Trinity point, and it happened that  when I zoned for residential in the boundaries of a high-wealth zone effect(provided by the aquarium plaza on the left) some kind of lake originated instead of a building. At first I thought.. Ok..maybe it is some kind of high-wealth pool.But honestly I think it must be a bug. I can't bulldoze it and can't query on it. It's indeed a lake and not a visual glitch because If I try to build a road on it a pop-up message notifies me of wrong bridge placement.

I am not using any mod, just the vanilla simcity with the official DLCS.

So, has it happened to you before?

Regards.

 

EDIT: Oh wait after inspecting the lake I found the building using my x-ray vision(Happiness MAP). It is in the bottom of the lake.. COOL
PD2: Lakebug2 is a gif(so the low quality)

EDIT 2: Bulldozing the now clickable mansion beneath levels back again the terrain
