We have some more details about this patch note - this change made more Custom (orange) items available for reverse engineering, but it currently does not include crafted Custom items. We will be adding the ability to reverse engineer crafted Custom items in the future, but that functionality was not included in this change. Sorry for the confusion; we're updating the patch note right now.
I can reverse engineer my War Hero crafted oranges.
Which is a "Crafted custom item" - which you claim cannot be REed.
