(New) Problem in Developing Ilford PanF+ in Rodinal

I just developed the last 2 rolls of a 12 roll project shooting Ilford PanF+ at ASA 32 and developing in 1:100 Rodinal, and encountered a fogging and "splotches" problem on just these last two rolls.

See below for an example:



Notes:
The temp is always 20-22C and I adjust the time accordingly. (from 13.5 minutes for 20C)

I have used the same stop and fix (Kodak) throughout...I wouldn't think this was the problem since the last two rolls developed were fine,although I probably don't change these solutions enough.

I do not re-use the Rodinal.

The ambient temperature of my darkroom(bathroom) has dropped a few C's, so maybe the Rodinal precipitated (I thought Rodinal was always this way though).

I seem to remember usually shaking the 125mL Rodinal bottle vigourously before use, and don't recall doing that when the problem occurred.

The film is loaded in complete darkness, the stop and fix are added in almost darkness.

I use a plastic 2 roll Patterson developer.

Both rolls were at below freezing levels in strong wind and right near the ocean.

I can't think of anything and would hope that someone with a lot of experience can look at film and know what happened.

Thank you,
Andrew Albright
