Bug: Water inside

The top level of my base is partially underwater, partiall above, so I can see above and below surface through windows. The bug is that the room almost always shows waves inside the room, but sometimes not everywhere - my bedroom behind an interior wall and door stayed ‘dry.’ This also affects furniture placement as while using the creation tool the wireframe image will appear sunken into the floor and waves make the wireframe turn invisible - actual placement still works fine.

Yeah, the feedback tool in game is meant for that, not this website.
