UpdateHandler Line 72 Exception thrown: 'System.IO.EndOfStreamException' in System.Private.CoreLib.dll

WowPacketParserModule.V1_13_2_31446.Parsers.UpdateHandler Line 72=>90=>153 Throws an exception which prevents any CreateObject1 or CreateObject2 version of the SMSG_Update_Object to not be output.

I inserted a _=packet.ReadInt32(); at line 148 which seems to have fixed it in some cases.

This is reading a parse from the latest release of WOTLK Retail version 3.4
