Funnily enough, the recent comics have added all kinds of hijinks to Fett’s life between obtaining Solo and delivering him to Jabba.

From what I understand, it is indeed stupid

Guess it is fair enough not to show Boba delivering Han after all. You’re right about the taking 1 year to get to Jabba bit. It actually reminds me of reading Shadows of the Empire many years ago with what Boba already went through, evading other Bounty Hunters to get to Jabba in the first place.
