That is strange, the npc should have spawned. The spawn script was writen so that every time you enter the module it would check for the conditions and if true the npc would spawn.
i'll get the alternate appearance.2da out today so the the nemo problem is fixed.
Or you can install holowan plug-in the fix then this mod.
edit: the sources folder is only the source scripts used in this mod there not needed for this od to function but are there for other modders.
