Did not recive skin after killing Compiler

Killed the compiler with a multi team lobby. Did damage and also activated monitors during the fight. Videoproof is available if needed. This took a lot of effort and work and not getting the skin after killing compiler is really frustrating. If I could get some help with this would be appriceated. Edit, I have done it twice now, and still did not get the skin. Even have the gangleion exfiled and completed in the codex. Both times I killed him I was playing destroyer.
