This was first noticed when I drop one elk(butchered) in village and left for the second. When I came back next day I cannot found the fat of first elk during tanning.
This isn't a great deal but the thing really caught my attention is that when I collect the dried/smoked meat I when for 'donate' 20% as using fee and found the calculation isn't right, some meats are missing.
At first I thought it could be wildlife but it happened so often and I went for some testing. Turns out if you left food (meat/fat, not sure about fish/veg/bread/etc) in the village, the inventory will consider them as the property of the village and consume 1 from each stack.
I tested it with leaving 5*5 smoked cut in a house, 5*5 outside that house, 10*2 in another house and 10*2 outside that house. I returned in an month and a half and each stack have a missing cut(4*10+9*4).
The other effect is that the inv system will treat those tiles as food storage and spawn new foods on those tiles.
Not sure if dropping weapons/clothes/furs will trigger similar effects.
