I don't seem to be getting count increases for the Silessa's Battle Harness chests, or for the Night Fae Summer Wilderling in Korthia event (I am definitely Night Fae when trying as I am the one clicking the drum to summon the rare) - I have downloaded and applied the 10.0 patch from Curseforge

I suspect the changes made in #496 broke tracking for world objects (I only tested fishing as I was short on time).

Since Blizzard removed the event used to track chests, we may have to find a new way of detecting when one is looted...

Cannot reproduce, seems to be working for the Night Fae one.

I couldn't test the Venthyr item, so maybe it uses a different mechanism?
