Speaking of which, anyone else bothered by Han & Lando suddenly being cool again in ROTJ despite their last meeting in ESB?

I recall a cool moment in the script (I think during the deleted sand storm scene) where they sorta spoke on things and came to an understanding.

LUKE (moving to his ship)
I'll see you back at the fleet.

HAN
Why don't you leave that
crate and come with us?

LUKE
I have a promise I have to keep
first... to an old friend.

Luke and Artoo take off in their spacecraft.

HAN
(looking dubiously at Lando, obviously
remembering his friend's betrayal
and subsequent aid)
Guess I owe you some thanks, too, Lando.

LANDO
Figured if I left you frozen like that
you'd just give me bad luck the rest of
my life, so I might as well get you
unfrozen sooner or later.

LEIA
He means "You're welcome."

LANDO
Come on, let's get off
this miserable dust ball
