FWIW, I downloaded the original TIFF images. Did CPFind, Find Vertical Lines (it found none). Optimize Positions (incremental, starting from anchor), Clean control points, Optimize Everything without translation. Optimize for Low Dynamic Range. Set it to rectilinear projection, full size. The stitch came out just fine.

That's a very peaceful looking neighborhood.

I did learn a bit: I feel reassured that my present laptop (2.4GHz 4-core/8-thread i7 with 16GB RAM) could handle it, since I'm hoping sometime to replace my present 6MP DSLR with a 24 or 36MP one. I've been eying the new AMD and Intel processors, wondering if I'd need to jump to one of those. I have a couple of strip panoramas what cover many miles of coastlines (some in Hawaii, some in Canada), so nice to know I'll still be able to process such panoramas with higher resolution images. :)

Here's a downscaled version of the 24202 pixel wide stitch. Hugin 2017.0.0.eac5e8cc546e on Windows 10 Ent 64 bit. Don't see any problems. CPFind, added some VCPs, position optimization, remove outliers, position optimized again, photometric optimisation, stitch at maximum optimum size.

            Hello

            Here is a scaled down picture, produced with hugin
            2017.1.0.64cc39ce23d4 . The result doesn't depend on the
            type of blending software - internal one or enblend-mp and
            enfuse-mp are used. The scenario was - loading pictures,
            CPFound + Celeste, geometrical optimization (positions),
            fotometric optimization (LDR), adding several vertical lines
            and automatic straightening.

            I recall it is the second time I see the similar output. The
            previous was more than a year ago.

            If needed, I can provide with original tiffs.

        I can't see anything strange in the pto file. And with dummy
        images I can't reproduce the issue.
        Can you test if the remapped images are okay and the issue is
        with the blender or if the remapped images are already buggy (on
        the stitcher tab select remapped images)

        One more idea: Have your images icc profiles embedded? If so
        check the icc profile for the red image.
