Here is a good reference image for what I am about to go over:

 

As you see from my next attachment I picked up and returned the fruit looking icon back to the same spot as I pulled it from.

 

1) Despite the fact 'Weapons' is selected all object in my wizards inventory lost their haze/fog for not meeting the requirement.

2) The haze/fog effect only returns if the player makes a different selection like 'Armor'

 

3) If you also notice my 2 handed classed specter the second slot is not hazed/fog here in the image. This is because when I picked it up and returned to the slot the 2nd slot was not reapplied.

Still happens with this build 364
