It's exceedingly difficult to get things flat/right-angled and symmetric in this game, OP. The blocks are all whole-number-dimensions but they often fit in in weird combos, things can be shimmed fractions of a meter accidentally by the inclusion of some other elements for better or worse, and yes, the terrain changes made it harder to get flat ground, and no they haven't been reversed. The meme that the old system was a technical error that was resolved was selected for even though its counterpart (breaking down a whole column of terrain for a fraction of the stone it's worth) remains in the game, evidence that it was never a bug in the first place but a mechanically consistent strategy that was removed to add more work to the gameplay loop.

Just take a look at the Reddit; if you like the structures you see then you're pretty much assured that you can get it done somehow in the game. If you'd like to build something more than cottages, longhouses, Rice Krispie castles, bobsled tracks, stick figure trolls or wooden sculptures out of item stands you may want to look for something more robust though.

The changes in the game generally don't come as a result of community input, they just kinda throw them in there and let the naysayers say nay elsewhere. No problem with that? Buy right now, otherwise -
