NullReferenceException (Can someone decipher this output log?)

[Odozer]

I've tried to reload my save game a few times and get three errors in the console, Checked the output logs to try and understand them but I don't know where to start after reading them. Could someone tell me what the issue is and how or if it can be fixed?
