I've noticed that since the weekly update, there is a DZ Supply Drop that is Bugged in DZ South.
Platform: PC
Region: US - West
It's just west of the Stockpile landmark and east of the Safe Room in DZ South. In the area with the big cylinder silos. The icon for the supply drop always appears in that area and on the map it has the yellow outline as if there's a supply drop there. There's no timer in the DZ, so the supply drop isn't ever active.
When the supply drop is announced for the DZ, you can go to the area and you will encounter Black Tusk in that area always as the map indicates it's Black Tusk. But there are no supply drop crates available in the area.
Attached some screenshots showing the issue.
