Have a working puzzle lock
This happens quite alot especially with the bigger sizes which i play almost exclusively, i will have the pieces locked in place but the puzzle will often unlock itself and jump around anyway, its offputting expecially whe. The preview is turned on
YES, please! This is exactly the suggestion I was going to post. The lock puzzle works...except for when a piece that fits gets too close to its spot. Then, the whole puzzle forgets its place and runs to the single piece! The lock puzzle feature needs to have a weighting order or order of precedence, or whatever you call it. So, whenever the puzzle gets the "join these two together" code, the edges, or the bigger, joined section, stays put and the smaller joined section or single piece does the moving. The only time the whole puzzle doesn't move for me is when I very carefully position a piece in just the right spot. I only choose the max number of pieces, so the unlocking frame happens to me at least 10 times per puzzle.
