By the way, this bug is still alive and kicking. For me, grey in collections tab, but are available to slot in armor are: HEAD: Primary Ammo Finder, Special Ammo Finder, Heavy Ammo Finder LEGS: Primary Ammo Scavenger, Special Ammo Scavenger, Power Ammo Scavenger GENERAL: Taking Charge (Season 9), Shield Break Charge (Season 9), Empowered Finish (Season 9), High-Energy Fire (Season 9), Global Reach (Season 10) Too bad I can't specify how it happens for replication, but it's clear that it also affects the new mods.

I can confirm that the bug does exist. The ones that I have noticed so far are not showing in my collection but are available to be applied seem to be "Earned while Leveling" mods. If I captured it correctly, in my case they seem to be: - HEAD: Precision Weapon Targeting, Scatter Projectile Targeting, Primary Ammo Finder, Special Ammo Finder, Heavy Ammo Finder - ARMS: Fastball, Light Arms Loader, Rifle Loader, Large Weapon Loader - CHEST: Unfinching Light Arms Aim, Unfinching Rifle Aim, Unfinching Large Arms LEGS: Light Arms Dexterity, Rifle Dexterity, Oversize Weapon Dexterity, Primary Ammo Scavenger, Special Ammo Scavenger, Power Ammo Scavenger - CLASS: Distribution, Absolution, Snapload Finisher - GENERAL: Arc Resistance, Solar Resistance, Void Resistance, Minor Resist, Major Resist, Boss Resist, Taking Charge, Shield Break Charge, Empowered Finish, High-Energy Fire I think Arc Resistance, Solar Resistance, Void Resistance, are the only ones that seem to have an energy type in the entire list.
