This have happen on 0.51 and 0.52 patch

Sometimes, when i got raw meat on backpack and start new game next time, some of gears and all meat have disappears.

First time (0.51) i got raw human flesh, whole backpack have disappear (hunting backpack)
Second time (0.51) i got also raw human flesh and half of items and all meat have disappear (hunting Back0pack also)

Now third time i got raw cow meat and guts on tortilla backpack. All of those and some gears (map and other) have been missing now (23.12). But meat in pot still remains.

Not sure, what is happening, but it looks that there is a pattern?
