[casswedson]

Summary

None

Purpose of change

    "entries": [
      { "item": "backpack", "contents-group": "small_bugout", "prob": 100 },
      { "item": "daypack", "contents-group": "small_bugout", "prob": 100 },
      { "item": "backpack_leather", "contents-group": "small_bugout", "prob": 100 }

At the moment, we don't handle things like "item too big for container" per itemgroup entrie, the game just trows an error. see link

Thanks, I ran quite a few tests on the small bags and thought they were safe after a lot of tweaking.
