What gets Destroyed?
Stepping through it in order.

Start - Nukebot with Hang in There are on a base

Play Sacrifice


Choose one of your Minions - Choose Nukebot
Draw Cards equal to its power - draw 5 cards
Destroy that minion - prepare to destroy Nukebot, check Ongoing triggers
Hang in There triggers on If this minion would be destroyed
Move the Nukebot to another base
Destroy Hang in There


The trigger on Nukebot never fires because it is never destroyed.  The Hang in There prevents it.
