Yeah I noticed last night that those shaders had disappeared again and figured they'd locked them back up because of the loadout bug.
And speaking of shaders, has anyone only just started getting shaders for the hammerhead rifle/never gotten anything from Dutch in loot boxes? I got Dutch day one but had never gotten a single one of his shaders from the loot boxes before so I finally figured I'd just unlock one of his shaders with veritanium, then after that I got about five or six hammerhead shaders from various crates for the first time ever.
It feels like unlocking that first shader manually sort of jolted the game into realising "oh yeah, you should be getting shaders for this stuff too." Either that or it's something they only just fixed along with locking up these cursed level 10 ones. Though I've still not gotten any for Dutch himself from the loot boxes either, so it's still not working completely.
