Ahh, I'd already used one on the pine forest. I used them on pine forest and inside the cave. Is there another ember heart I can access at this point, or am I stuck without the chest/without the sawmill working?
I have updated with a new build with a few Qality of life changes chests can no longer be looted if your inventory is full or you cant carry the item. sawyer is now there by default so you dont need an ember heart to do his quest. mushrooms in the mines now keep track of there state and are saved. the UI text is now all using the same font. will hopefully get an update tomorrow with a fix to the sawmill and forge not saving items that are left in them. hopefully this helps and you wont have to start over :)
