Noxious Remedy button

[Phaso]

This appears to have been quietly fixed, at least for the Focused Noxious potion.

I believe the "item is no longer in inventory or doesn't exist" is because of how the cure button works, it will use Focused or Dedicated (T8) cures from my understanding of it, it likely tries to take advantage of the queue casting system to cast the best one, but will show the error if you don't have any of the other type in your inventory, such as carrying Focused but not Dedicated.
