I actually had something similar happen to me recently, and it so happened that I had a 120 roll of APX25, and a bottle of Rodinal that had a brown slush that would rattle if I shook the bottle (which I think meant that parts of the developer had crystalized).
Anyway, I developed it with a 1+50 dilution in tank, agitating 5 seconds every half minute, and to my surprise, the negs came out looking quite normal. Can't really tell them apart in density, sharpness or grain from other APX25 negs developed in fresh developer.
Was a fun little experiment.
