It is common among some of us
I developed it in ECN-2 kits, custom made in Moscow. And in regular C-41 kits. No difference at all.
Before developing, washing soda to relatively hot water and shake like crazy.
After developing, washing, clean with fingers and water to get rid of the rest of RemJet and then PhotoFlo.
Colors are odd, but some claims to like them.
But none of them are switching to it long term, it seems. Expired ECN-2 is very lomography.
ECN-2 was good BW film, but prices went up.
Google ECN-2 film developing at home.
