Inventory overflow boxes are placed in a row

Hello,

nearly all overflow boxes from different bots and different definitions of bots are placed in one row like pearls on a string. The line is exactly the horizontal half of the map, from west to east. When the inventory if full, the bots may run over the whole map just to go to this spot and place the box. My partial config:

"Inventory overflow": {
        "Stash setup (bot will put items in the stash)": {
          "Enable?": false,
          "Hide stash?": true,
          "Life time (0 - will exist until restart)": 3600.0,
          "Maximum amount to use (0 - without limit)": 10
        },
        "Box setup (bot will put items in the box)": {
          "Enable?": true,
          "Use small box?": true,
          "Box skin": 3565696561,
          "Life time (0 - will exist until restart or until it dies)": 10800.0,
          "Maximum amount to use (0 - without limit)": 5,
          "Another container prefab (you can leave it empty)": ""
        }
      },
