What are the "faulty crafting recipe and items" to remove ? (stated in Palace of Ice update notes)

The update notes for Palace of Ice says : "Removed some faulty crafting recipe and items from the Dungeon Maker, such as the scroll of Warding Bond or the duplicate crafting recipe for Potion of Healing." 

I therefore removed the Warding Bond scroll and crafting manual from my DM (called Your Headquarters...).  Though the update no longer offers it as an option in DM, it was still on my merchant as such and still in the published map. 

Request : it would be useful, for all DM creators, to know which other scrolls and crafting manuals should be removed if they are faulty or can cause issues.
