Making timber piles; I was sure I put rocks in first and built the rocks in a few days ago just to hold the spot. So when I just checked and the timber pile had no rocks and no boards... ok, well, let's finish it anyway.

So I added boards and 10 more rocks to this shell of a signpost, and when building it went to ~115% or so.

Maybe I'll get some petrified boards

Judging by your explanation it decayed off claim.

To clarify: I built 10 rocks into the signpost, off claim, to hold the location - no boards added. Then later on went back and ignored the fact that it had 0 boards and 0 rocks, built in or otherwise, and added boards and eventually rocks to then build the structure. The build went to ~115% to complete. Not sure if built-in materials decay, but rather it seems there was a bug where it thought there were 20 rocks when I finally added boards and built the thing.

I just said that they do.

This has been known for a long time. Your built in materials can decay off claim but the game still counts their percent when you build again, so it can go over 100% before it reaches the real 100% built. We've never considered it a bug, though I suppose it technically is.
