PrimeNet also won't assign pointless work, now or in the future. If you want to do pointless work, I suggest setting the nearest bundle of cash on fire.
So it can either 1) assign nothing at all, with an error message, which is admittedly probably the better choice or 2) assign a similar worktype with the same purpose, which is what it did. If you want factors of M1277, that's how you get factors. (Either that or pay several thousand dollars to the right people to run SNFS on it.)

mfaktc doesn't support nonprime exponents because the basic rules which it relies on don't apply to nonprime exponents (or rather only apply to the parts which are prime exponents), namely that
if p is prime, then factors of 2^p1 are of the form 2kp+1 for some integer k.
