Hi! Playing in official pvp 3610, it’s like 2day I can’t equip any kind of weapon nor armour to the thralls (equipment bounces back to my inventory) neither can equip weapons on my fast inventory.
Try changing your and your thralls inventory sort method to “no sort”.
As @Kikigirl mentioned if that doesn’t work try pulling your bracelet. Recently I can’t access God Breaker armor on Siptah and had been doing it for months have all the armor benches.
