CraftStore has been using it forever, but after Morrowind people have been randomly having issues with it no longer working. I'm finally experiencing this issue myself.
I have the crafting station open.
I need prosperous for light legs and the game confirms this:
In my bank in slot #206, I have
Code:
/script d(GetItemInfo(2,206))
As you can see, it is not locked and (as already mentioned) the vanilla interface can find it.
I was using CS to try to do it and it wasn't working, so I went direct:
Code:
/script ResearchSmithingTrait(2,206)
I do not have ESO+ so we know for sure it is indeed BAG_BANK for me.
...and then nothing happens.
