I would guess display purposes. Displaying "0.99999" in the UI is ugly, yet if you round the display (only) off then two people might see the same value in the UI but the actual value is different (eg., you can't tell someone "I had water height set to X").
So the landing animation looks a lot nicer now, but also makes we wonder what happened to the idea with the egg?
On OSX 10.9.4: first game froze with server crash around 7:40 doing nothing special landing animation looked broken with lots of flickering elements performance stats always show inside PIP if displayed second game died with server crash third game moon orbit seemed to decay and smash the planet in slow motion without leaving a crater performance seems worse (will grab performance stats next time)
They added it about 1 or 2 pte builds ago. I can get it to spawn pretty consistently in certain conditions as well. It's always out of order though.
Just noticed, where have all the naval models for buildings gone? Please don't scrap them! Edit: Galata turret has trouble hitting pretty much anything. And scrolling is still problematic.
