Heyo. Basically, have the same problem. However, I've managed to track the source of the problem. It's bonded to number of total .npc files. I have empirically discovered the threshold of max model (vehicle/player) mods installed, in which case if I would place any other model mod above it, it would render the same mistake - losing ability to spawn stormtrooper NPC. Then I've taken the content from random mod .npc file and merged it into another, rendering the loss of 1 .npc file. Problem disappeared, while I was still allowed to use merged NPC. UPD: While I was writing this post, I've discovered that I can't spawn several other NPC's below stormtrooper in alphabetical order. I still can spawn alora, alora_dual, kyle, stormpilot, stormtrooper - but not swamptrooper, tavion_new, wampa etc. I don't know what the heck is causing this, but: 1. I'm using JAEnhanced and dropping almost all mods into jaenhanced folder instead of base. 2. I'm renaming the names of mods, placing a short description before them, like map_, model_, saber_, weapon_. And I have a lot of them. 3. I'm using the Outcast/Academy merger, tweaked for using inside JAEnhanced. Any thoughts?
