I was serching for some apples in Gvozdno (Dec. 26th, 20:13).
I think I tried it 10 times and got 3-4 apples. Then I switched to my inventory and saw 30+ apples in the vicinity window.
I've tried to reproduce it on the neighbor tree, but it didn't work.
You can find the location of the tree in the following picture. It was the one in the middle.
