I decided to have playtrough without HMI (I noticed what White Dwarf always spawns in Tabitha system from HMI, in every playtrough when I had both mods enabled), and I reduced reduced sector size and star constellation count, maybe this script needs failsafe if its unable to find fitting system for spawning boss? Its seems that generation wasn't able to generate needed systems.
