I forgot to mention that there is a issue with a particle:
the editor wouldn't launch because one particle missing:
it asks for:
texture = "mod_assets/cultist/textures/monsters/cultist_fog.tga",
texture = "mod_assets/cultist/textures/monsters/cultist_smoke_01.tga",
texture = "mod_assets/cultist/textures/monsters/cultist_cloud.tga",
and there is no one
did you forget something?
