I got those with Neopan too just a couple of weeks ago ... and I
_usually_ don't get them (I have a couple hundred rolls of Neopan in
stock for 120).

The only thing I could pin-point was that I used HCA on that occasion.
I didn't do that anymore and I don't have them now either. That
doesn't really mean it has anything to do with it. It might have been
something else totally, a one-up kind of thing.
