AP1100AE needs exorcism (DEC turned all the way around like Linda Blair)

I was doing a three point polar alignment in NINA, as I do every night, and when it started slewing (usually a small movement to be just off the pole), the DEC axis spun clockwise (as viewed from behind/above facing north) all the way around. I finally hit stop, but not sure if I stopped it, or if it actually got to the right place by going too far.
Thank goodness for thru-the-mount cables. Interestingly when I then did a park 3 it unwound. Find home went to the right place. I started all over and it worked fine. I tracked this down in the NINA logs and it was just a slew, like any other slew. I tracked it down in the ASCOM logs and got this: 035328 2022-01-17 18:19:58.285: ASCOM: Info : SET TargetRightAscension = 3.88285751697392
035329 2022-01-17 18:19:58.285: ASCOM: Info : SET TargetDeclination = 85.2108975166604
035330 2022-01-17 18:19:58.285: Telescope: Info : CommandString TX=':*SLEW,3.88285751697392,85.2108975166604#'
035331 2022-01-17 18:19:59.300: Telescope: Error : CommandString: NO Response or bad APCC response: ':APCC,4102,*SLEW,3.88285751697392,85.2108975166604#', Response='*SLEW,3.88285751697392,85.2108975166604' -> Giving up!
There are no comm events shown on the APCC screen. Nothing I can make sense of in the APCC log. Ray, attempting to anticipate, logs zipped and are here: https://drive.google.com/file/d/1dpOb6Hw8JwcC0MoHzXXiOV-oX1MEO2eR/view?usp=sharing That's taken from the mount after 2 restarts of NINA but no restarted of APCC nor did I re-initialize the mount; the 18:19:58 event and subsequent LONG slew is the one of interest. My first thought was I had confused something with a bad unpark or such, but Park 3 immediately afterwards worked perfectly, as did Find Home, another Park 3, then I started NINA and did (+/- movement due to time) exactly the same thing and it worked fine. It sort of looks like Ascom and APCC had a disagreement. Did I do something wrong? Linwood
