Groundworks

Players

• A Stretch is refused whole, laying and charging nothing, when a claim mod guarding the place event protects any position it lays, as a Fast Replace and a footprint already were. The preview asks no claim mod, so it draws such a stretch accepted and the click refuses it.
• Each block a Stretch lays, and each block an Assembly lays besides its Key, now counts as placed by you, for the placed-block advancement among others, as a block placed by hand or by a Fast Replace does.

Consumers

• Refusal.Stretch.MAY_NOT_BUILD also refuses a stretch where a protection mod cancels the place event, which Groundworks fires on the click for each position of a stretch that would otherwise go through, and never in the plan the preview asks.
• A Consumer's block that a Stretch lays, or that an Assembly lays before its Key, now gets Block.setPlacedBy with the placing player and the item it was laid from, as one a Fast Replace lays already did: a Stretch's once all its blocks are down, an Assembly's once its Key stands, and only where the block still stands. The upper half of a door or a tall plant, and a bed's head, is not told, as vanilla tells only the half it placed; this holds for a Fast Replace too.
