P.S. Something that had been on my mind while making this post, and unsurprisingly came up pretty quickly in chat elsewhere:

Yes, there have been many complaints about things being too ruined in the past. Of course that's totally valid for other tiles sets that could have cleaner pieces, which lend themselves more to building clean houses, etc.

I did wonder if those past complaints were a reason for the U49 Stone Nest set being as pristine as it is, and I (for one) don't mind it staying as-is. This is very specifically a request for new, ruined Stone Nest pieces in future updates, not changes to the given set. Because Stone Nest in particular lends itself to fun ruins & adventure builds (especially when combined with matching Antiquities like the Stone Nest Pendulum). Stone Nest is the perfect tile set for ruins, with beautiful textures, colors, and piece types we don't already have. I think it'd be a huge missed opportunity not to include these!
