Hey,
Loadouts cannot reliably change yellow or green armor mods on class item:
I have 2 loadouts with the same class item. One has empowered finish and time dilation, the other one has Benevolent finisher and Distribution.
If I put empowered finish and time dilation on the class item and then switch to the other loadout, it only swaps Time Dilation for Distribution (those are in the same slot), but it doesn't switch Empowered Finish to Benevolent Finisher (probably because they are mutually exclusive when putting together.
The loadout says "Contains items with invalid mods" by the way, but there is no reason why this shouldn't be allowed to work.
