KOTET Chapter 5 Colossus Droid Fight HP Bug

Hello there,

I'm playing the Story mode Chapter 5 KOTET on my Smuggler for the first time, about to do the big robot fight (where you've entered the robot and you're in control). The robot has my characters' HP, which means I get instantly killed by the 200 enemies coming through. I have reset the mission multiple times on different difficulties but can't seem to get the sequence to give me the appropriate HP. Even on different endurance levels to change the hp value. It even shows that I've loaded a rocket on my character when resetting the mission. Anyone have this issue before? Or potential fixes maybe? Thanks
