Rapid-fire Replying to myself because as soon as I read the comments and booted the game I remembered some stuff my ADHD ass is inevitably gonna forget:
Save issues: Looks like it's not just me, but the issue is most pronounced on lower-end hardware. Just saw Squirrels's comment.
Enemies not dying: Another thing that has sometimes triggered it is having enough walls/structures built causes enemies in the enclosure to stand still - I noticed this when I built walls around the starting town on one of my saves in 0.34 to protect them from the dominion, and I saw many of the ghosts, frogs, etc just... stand there and eat hits, even out in the open. Just saw something possibly similar happen with a wraith in my save, which made me think of it.
Compliments to: The cheese magic system. Seriously, the fact that casting the spell lets you specialize and get some perks is super cool, and makes the magic of terroir feel not just like drawing power out of the land, but out of cultivating your own relation to it! Would love to see the concept expanded on, maybe through like affinage, or perks of some kind? Come to think of it, Terroir is also heavily associated with wine... Similarly, casts are often pretty limited and inventory can be hard to manage - maybe like a utility belt slot, where you can hold some smaller wedges? Or even like profession tailored pouches, (E.G. Caster's pouch, gatherer's pouch, hunter's pouch, etc) which can help you hold specific kinds of gear? Backpacks seem a little impractical and are probably already covered by pack animals, but having some playstyle-specific utility could be cool. Just spitballing though, and for all my Ideas, I've found even more pleasure being surprised by the things I wasn't even expecting every update, so above all take care of yourself and keep creating the game you love, and I'll be happy to taste the samples!
Let me return to this reply to address the more substantive reflections about Terroir and affinage - absolutely agree, and I have added your comment into my notes for the future work developing these areas. You're right - it's a rich vein waiting to be developed further. In the meantime, I've made some immediate changes in this patch to address some of the more mechanical stuff - e.g., adding more backpack upgrade options that are easy enough to find from NPCs and from loot drops. You'll see in the devnotes for 0.3.8 that there's a lot in there thanks to your suggestions
