Yep I returned it, trying to figure out how to actually make the ground level and that having ZERO feedback on top of having more roofing problem just nope. The building in this game is just awful and completely unintuitive. I'll try it again if they ever revamp their snap system to be something more normal for these types of games, otherwise it aint worth the frustration.

I remember having same issue with the snapping of pieces being off set. I was told to use my F6 and F7 keys to get the off set back to normal. As for leveling the ground make a Hoe to flatten or fill holes.
