I think I've found a bug here: if the order is set to 'order by decreasing deviation', I scroll to the top, and press run (play) on a step, not all pages are processed.
Can this be confirmed?
If so, is the processing queue being modified as the process runs, moving some pages before the current index and thus missing them?
Finding bugs in GUI software reliably is kindof hard; sorry if I'm just making a mistake.
Scantailor and scantailor-advanced are amazing software, thank you!
