Swamp Planet Features (Large Trees, "Yoda huts") move location

[Aphasia]

So, I've recently tried building on the new swamp planet locations and have discovered that if you build something inside one of those new dome structures (best description I can give is "Yoda's house on Dagobah") when you then save and reload your game your items will be in the same place, but the hut structure has moved several yards away. The same seems to be true for those gigantic tree stump overhangs... you can't incorporate those into your base because they won't stay put. This behavior doesn't seem consistent with other non-resource terrain items (ie, items you can't mine, they're indestructible land decorations).

Can anyone confirm? Is this a bug we can fix? Would like to be able to build these into the base/account for their presence.

I think those recalculate their position everytime you load the planet. The algorithm keeps them in the same general position, but they move around slightly.
