This will be bugs I’m seeing. No need to reply unless you need more details.
Pieces that I lock together that are not in their final position don’t stay locked together. fixed
After I finished a puzzle the app wasn’t acknowledging it as solved. I grabbed the finished puzzle to drag it around the screen and about half the puzzle (random pieces from all over) moved around leaving the rest in place. This could be the reason it’s not showing as finished. I haven’t been able to reproduce this behavior.
Toggling the piecebar can pull pieces locked together apart and back onto the piecebar. fixed
