Probably not applicable to this current world, but hopefully something for the next one. In world 10, there were statues scattered across the world depicting an event from every previous world. You should definitely bring those back, and introduce more for the worlds that happened since then. I would also suggest placing non-constructible unique roman-style pillars around them, possibly liftable, something like an ancient roman temple or villa etc. and non respawning scavengable treasure piles. It would explain why we have some mediterranean native plants, like black pepper, thyme and (somewhat) lemons, as presumably this game takes place after a 'roman' occupation and subsequent withdrawal. I would just like to see some sort of 'ancient' presence, would be cool.
Statues are still around, found the one for w6 a month ago

We found the salem statue this world. They exist but seeing one isn't something that tends to happen every world in my experience unless you know where they are and go looking.
Lucky: haven is so quirky Lucky: can be so ugly, can be so heartwarming Sevenless: it is life
+1 I would love some uncraftables artistic objects like pillars, broken statues, from an ancient lost civilisation scattered around in haven and hearth as collectables. Maybe even make them in to a pusle of some sort, making it more worthwhile to collectables them.
