After I place some community lots, I've noticed that the terrain paints are not in sync with the building. The ground has shifted slightly away from the buildings and objects. I can certainly go into build mode and re-paint things, but its a time consuming process I'd like to skip if possible, since I usually place many buildings at one time to prep a world before playing it. Any ideas on how to keep the problem from arising? Its happened on EA pre-built lots as well as a few custom content lots. Houses as well as community lots.

Yeah, it's just how the game works, there's nothing you can do about it. It happens when a lot is rotated during placement, so in theory you can avoid it by never rotating lots: unfortunately, though, that's totally impratical.

That is most unfortunate. Thanks whiterider.
