I didn't receive a skin for killing the compiler

Yesterday. On May 30, a group of brave runners of 11 people united and together killed the compiler. I was in the room and dealt damage to him, but when we all evacuated together and divided the loot, I was not credited with the kill and I did not receive the skin. Is it possible that because there were 11 of us, not everyone received the skin? Or is it a bug? If it is a bug, will I receive it later?
