I'm guessing it's not being seeded....

@jgoeders I believe it is being seeded. I checked the log files for the bit/wire swaps and the same bit/wire is being flipped each time the flow runs.

@yonnorc42 I thought I had linked a case where it was causing the CI to fail. Do you remember where that was? Can you add the link here?

I restarted the CI and it passed, which is why I was convinced something was non-deterministic.

The weird part is that I checked and it is being seeded. But on occasion a different wire is flipped anyway. I haven't looked very deep into it yet so I'm not sure why.
