There is a bug in the bird side mission. I can place the bird cage but I can’t find it again and not only bird cage and also any item I drop under that tree those are happening at under the tree which is the right side of the mission area
Yep. Exactly where I lost my last bird cage. I placed it and turned around to ride away. 30 seconds later, once the bird song ended, I returned to the tree I placed the cage next too and the cage was gone. The map in the journal still shows where it is, but it isn’t visible.
