My guild killed Gothik last night - it shows on the logs and the progression pages for our server. However it doesn’t show on my character page in the parse section - his name doesn’t even show up on the list of Naxx bosses - but he does show up in the little graph at the top of the page.
I’ve checked several people in my guild - same thing. I checked other people on our server that haven’t killed him - same thing. I checked on a guy from a guild that is 15/15 and it does show on his sheet.
Here’s my character page (Gothik not on list)
