As for the stone piles, I've always received the 50 back from it, same with the wood

I've had a handful of wood/stone piles break and only give me 1 back, uncommon and usually people respond with. "Was it full health?" or "Did you repair it first?" but like, I store them under cover of a little shed and they're all full health.

And yeah, stone burns sooooo fast it's almost depressing later on in the game.
