Some images get stuck in the NIC (staging and prod)

While processing groups of images through the E2E workflow, occasionally the odd image gets stuck on the NIC step and cannot proceed. I retested these image in another batch of images, as well as on their own and with different models, and repeated these steps on production as well as staging. I have halved the images just in case, and still met with an NIC sticking point. The images, while they are from the same section of MS73, are notably different from one another (my initial thought was that the images failing were images with poor parchment and bad ink, etc., but the errors do not seem to be consistent in this area).

@JoyfulGen I believe you also have a few images which do this as well.

I have attached two of the error producing images below (MS073_108, 110), as well as the relevant screenshot.
