I previously picked up the Elsweyr furnishing recipe for the Elsweyr Sarcophagus Lid, Ancient and when I later got the recipe Elsweyr Sarcophagus, Ancient recipe, the game says I already know that recipe. When I go to the enchanting crafting station, the sarcophagus itself is not listed. I am sure I have not picked up and used this recipe before. The game seems to not be able to distinguish between the two recipes because the names are similar. Had I not been taking screen snapshots of everything I learn due to a previous problem, I would have sold this recipe by mistake.
Here are the screen snapshots of the recipe that I have not learned but the game says I have, and what I can craft at the enchanting crafting station. The sarcophagus is not listed among the craftable items, but the lid is.
Please note that I did use the recipe for the lid so that information is correct.
