t = 0 frames are not saved in loading

            }
          }
        }
      }
    }
  ]
}

After load/dump:

{
  "modelId": "a",
  "loop": "None",
  "effectorTypes": {
    "": {
      "location": "World",
      "rotation": "World"
    }
  },
  "frames": [
    {
      "t": 0,
      "positions": {},
      "effectors": {
        "": {}
      }
    }
  ]
}

After some research, only t = 0 frames are not saved during import of motion.

Fixed in e2047c1, however I don't know how this was happened so I leave this opened
