Rocks and Trees in the east main river before the swamp, dissappear with one hit of the pick or axe. very little yield since only one hit.
Area bugged it east of scavengers berth, to north of salestich camp
I was getting this too tonight. It did the same with trees, bushes, rocks, mobs I killed. and no matter what tool I used; pick, skinning knife, sickle, etc
