Changes to be made until is fixed int Niflysharp

i) in NiflySharp - Niffile.cs - Load: .......

try
{
    // Create a new default instance of the block type
    if (blockTypeStr == "BSSkin::Instance") blockTypeStr = "BSSkin_Instance";  <<---ADDD
    if (blockTypeStr == "BSSkin::BoneData") blockTypeStr = "BSSkin_BoneData"; <<---ADDD
    if (blockTypeStr == "BSConnectPoint::Parents") blockTypeStr = "BSConnectPoint_Parents"; <<---ADDD
    if (blockTypeStr == "BSConnectPoint::Children") blockTypeStr = "BSConnectPoint_Children"; <<---ADDD
    var blockType = Type.GetType("NiflySharp.Blocks." + blockTypeStr);
    blockStreamable = Activator.CreateInstance(blockType) as INiStreamable;
}
catch
{
    // Block type is unknown
    HasUnknownBlocks = true;
    block = new NiUnknown(streamReversible, Header.GetBlockSize(i));
}

if (blockStreamable != null)
{
    // Read the block
    //streamReversible.Argument = null;
    blockStreamable.Sync(streamReversible);
    block = blockStreamable as NiObject;
}

if (block != null)
    Blocks.Add(block);

} ii) In Niflysharp - Niheader.cs - Addblockinfo

public void AddBlockInfo(INiObject newBlock)

{

  string blockTypeName = newBlock.GetType().Name;  
  if (blockTypeName == "BSSkin_Instance") blockTypeName = "BSSkin::Instance";  <<---ADDD
  if (blockTypeName == "BSSkin_BoneData") blockTypeName = "BSSkin::BoneData";  <<---ADD     
  if (blockTypeName == "BSConnectPoint_Parents") blockTypeName = "BSConnectPoint::Parents";  <<---ADDD
  if (blockTypeName == "BSConnectPoint_Children") blockTypeName = "BSConnectPoint::Children";  <<---ADDD
  
  ushort blockTypeIndex = AddOrFindBlockTypeIndex(blockTypeName);
  
  blockTypeIndices.Add(blockTypeIndex);

  if (Version.FileVersion >= NiFileVersion.V20_2_0_5)
      blockSizes.Add(0);

  BlockCount++;

}
