fc_lr_ss_elite
1st problem is that you have a brand new faction.
That by itself presents a whole mess of additional problems.
-New faction
-empathy
-initial world
---equipment, goods ---
-npcshiparch
-loadouts
-factionprops
(yada yada yada)
It's complicated and if you miss any single point where the information
must be added for the new faction, you'll get nasty "untracable" crashes.
2nd problem I see is the fc_lr_**_elite already refers to the Liberty Rogues,
so you have a naming/faction conflict. (unless it's a Liberty Rogue that you want
to frame for this setup)
3rd problem (possible) is the _ss_elite to signify your special purpose npc. You
have to make sure the npc shiparch, loadouts and factionprops.ini's have that
specific ship also set up for the fc_lr (group). d1-19 is basically irrelevant because
it depends on the equipment loadout you have specified for the ship. BUT,
if you want to have encounters set up in the relative system areas (such as around
Buffalo Base) you have to make sure the ship is set up to match the encounter zone.
In other words, he could be set up as a d19 who could wipe the floor with you, but
for the area, you have to make sure he's set up to show as a similar level in that area.
d1-d4 (or d5?). (So, you see that he's only a d3, but he's equipped similar to a d19)
