I will float two more hypotheses, which I did not see in the thread:
Hyp. 1: I will call this the "phase of the moon" hypothesis and it happened to me in the past. Each month, for a couple of days, my saddle would cause me all kind of grief. I suspect I was just more sensitive during said days... Unexpectedly, the lasting cure thus far was a new wheelset and plusher tires (Conti GP 4000 S, with 320 tpi).
Hyp 2: your weight loss may require raising the saddle just a smidgen to compensate for the loss of 'padding', so to speak. You might be sliding around a little more than before.

#1 is out of the question since I no longer have any remaining parts of my former reproductive system - nice not to have to worry about that
My fitter found last week that my saddle post was a smidgen too high (about 1.5 mm), so that probably would have allowed for it? Unsure, but Friday we are switching to a far less used version of the same saddle, so we will see. I do appreciate all of the input and hopefully switching saddles will take care of things until at least spring. That being said, I need to ride my mountain bike this winter for some gravel road riding/training, so if this does solve the problem then I will still have a decision to make...
