Different Characters = Different Scavenger Mod Costs
The Season of the Witch artifact perk that granted the below benefit, has inadvertently remained present on some characters that played during the season and used the mod.
'Diviner's Discount - All scavenger leg mods cost 1 energy.'
This is causing for my hunter to only require 1 energy and my warlock to require 2 energy, I am unsure about my titan. This is a very irritating bug that is causing for there to be discrepancies in my build consistency.
