Inscriptions are still not saving to spells or scales. Probably not to anything.
Craft something, anything inscribable. Put on an inscription. then either, relog, trade it to someone, put it in house storage, put it on consigner. You will notice the inscription is gone.
Tried t3 t4 t5 spells, t5 scales, but I am fairly certain this issue affects everything.
Old items I made and inscribed prior to this bug, still properly retain their inscriptions.
