Probably. Due to the lack of much experience, I was in doubt what actually happened to that old mix of C-41 chemistry. I was going to start a separate thread, asking if old C-41 dev can fog the film beyond recognition, but you sort of answered my question. I suppose that air-oxidated developer can get into the emulsion and attach to the dye couplers there, causing dense fogging.
