Using the INCLUDE tag within a pcc still produces "could not get reference manufacturer" type errors for elements within the lst being loaded that are not the ones being INCLUDEd.
ABILITY:@/pathfinder/paizo/roleplaying_game/bestiary_3/b3_abilities_race.lst|(INCLUDE:CATEGORY=Internal,Race Traits ~ Kami (Shikigami)|CATEGORY=Special Ability,Shikigami ~ Improvised Weapon Mastery|CATEGORY=Special Ability,Shikigami ~ Spell-Like Abilities)|!PRECAMPAIGN:1,Bestiary 3
produces complaints about a missing ABILITYCATEGORY for abilities that are not the Shikigami ones above.
To replicate, in Pathfinder mode load:
Advanced Player's Guide
Occult Adventures (latest version from NewSources, this is the pcc containing the offending tag)
It could be that this is "expected behaviour", but it's not very intuitive! If so, grateful for advice on how to fix without either 1) duplicating the B3 data; or 2) requiring the whole of B3 as a prereq just for one minor ability of one archetype...
