RA-4 oddity

[Stephen Frizza]

I was proofing on Ra-4 this morning and a paper jam occurred in my machine.
there was one sheet which looked processed and wet so I figured it would just need to be washed and ide feed it through the machine again to dry it. only on its second time through the machine something went crazy! and the attached sheet shows that has happened . I am curious as I am not able to replicate this result. anyone know what this may have occurred? and how to replicate it?

Looks like re-reversal. Develop, stop or wash, expose, develop again, then blix and wash.

IDK for sure. Could be Sabattier effect. I can't see closely enough to tell.
