I believe there was an original Marvel comic at the time that depicted Han losing his reward from the Alliance.
Yes, it was stolen by space pirates led by Crimson Jack, operating out of a salvaged Imperial star destroyer. (An operation Han later destroyed.) Han later saved Jabba’s life when a personally led attempt to capture Solo went horribly wrong. Jabba grudgingly forgave the dent.
Jabba was secretly funding Crimson Jack’s operation, and later learned Han was responsible for it’s end, and reinstated the bounty just in time for the ESB adaptation.
JEDIT:ZkinandBonez sort of beat me to it. 😉
