Bough of Melandru (Infused) bug
I noticed this bug/problem too when I infused it in a rush and didn’t pay enough attention to the crafted version. Not sure if we can get the old version back with the materials or something but the mystic forge craft version should be dissabled before others do this too.
Here is a reddit post link that has a picture of the infused version.

I made this backpiece, and the agony infusion slot was there, and the wiki confirmed it should be there. Why would you put 250 ecto into it when it already has the agony infusion slot?
The Wiki is clear and is correct.
