Worn/Sturdy quality Abyss Lord tomes drop with generic "GARMENT NAME" item names, and upon returning to the Tavern, are deleted from your inventory without warning.

NOTE: This bug was previously declined without comment, but is still occurring.  I am resubmitting it, as no explanation for its decline was given, and no response was made to my comments after more than a week.

Reproduction Steps:

1. Complete a low-level Campaign map as the Abyss Lord, particularly a loot-heavy map such as Throne Room.
2. Look for Worn/Sturdy quality Tomes
3. They will have a generic "GARMENT NAME" item name
4. Pick one up and return to the Tavern.
5. It will be deleted from your inventory, with a blank space where the tome once was

Screenshots: This first one proves that the generic-named tomes are dropping in the wild.

The same tome, in my inventory after picking it up.
