Something similar happened in R122 with my weaver. He had yet to build his workshop, went to place a bundle of fiber (or whatever it’s called) at the blueprint, then picked it up again and moved back to the stockpile to place it, but only after freezing for a bit. He actually put it just beside the stockpile, as well, making me think the carpenter in my original report wasn’t actually storing this item either, just putting it a little bit away from where he first meant to put it, which in that case just happened to be inside the stockpile.
The error message you see here I think is related instead to another issue.
