Patterning can get stuck on row n-1 and never finish

[Adrienne200]

AYAB software version: 0.99.0-rc6
Computer/OS: Intel Mac, Big Sur
Knitting machine: KH910
AYAB hardware: Interface

It's new in the rc4-rc6 timeframe, I've never seen this happen before.

Steps:
All settings and prefs at default, so Infinite Repeat is unchecked
You need to actually air-knit, Simulate is different and doesn't show the issue.
Open the Triangles sample. It is 10 rows.
(Optional: set the start row to 7 for more convenient testing.)
Start on the left, remembering to pause for two seconds after crossing the turn mark.
and knit as usual for 8 rows, noticing the end-of-row sounds from the hardware's buzzer and the "ding" from computer's speakers.
Keep going for rows 9 and 10 without slowing down.

Result: Usually it will select row 10 and complete as expected. But sometimes (about half the time on Mac, rarely on Windows but it did happen) I could get it to just keep repeating row 9 without ever finishing.

I've done a number of swatches with (recent) 1.0-dev firmware and not hit this, I think. @Adrienne200 are you up for trying it with 1.0.0-beta1?

[Adrienne200]

Still happening with the Beta 1 build. It has failed on 2 of my first 3 runs of the most basic test, the triangles sample with all settings at default.
I'll be testing with other machines over the next couple of days, to see if it's unique to this one machine.

Thanks for testing again. I’ll give it a try tomorrow on my 910 (from a Mac) with your exact instructions to see if I can reproduce it.
