Imagine the money you'd get from the Tooth Fairy if she found this sucker under your pillow

Here is one of the problems I'm trying to deal with. Placing a large 'Berg like the one seen below into a shallow area means that it will hover like this for a short while before slowly sinking into position. It's quite cool to see, but kind of an immersion killer
Sunken vessels also sink into the earth after a while, to keep Poly-counts to a minimum I guess. The Devs building-in this feature isn't a bad idea I suppose, but it was kind of cool to have the possiblity of crashing into a sunken wreck when trying to avoid DD's
