Fixing the setting of the wrong step is a lot of work, as I need to dig quite deep. But preventing the crash should be easier, as soon as I identify it.
Now, I could not reproduce the problem you describe with step 1 of the second track in the chain. I did record the bad step, but then I can turn it off, and back on, and step 1 of track 9 is doing fine as well. Hmm..
