Which setting has priority in the config.. CategoryStackSize or the ItemStackSize... I want the overall Attire Category to be 50, but have the Backpacks to not stack at all.
Priority of Settings
The priority is as such-
1. IndividualItemStackSize
2. IndividualItemStackMultipliers (Shortname first, then item ID. Multiplies IndividualItemStackSize if set.)
3. CategoryStackMultipliers (Also multiplies IndividualItemStackSize if set.)
So to answer your question, ItemStackSize would take priority.
