I tried several times in this game to have my courier ward as normal after level 15 (also mistakenly when I was level 14.. but ignore that). However the courier was always unable to use the wards as the item was muted in its inventory.

First put the items in at 27mins when courier was level 14.
Then at 37:40, I put some wards in and they are still muted even though the courier is now level 20.

Was there some kind of stealth patch affecting courier item use?
