No codex entry for Compiler Kill even though rest of team did.

Have killed compiler many times before and got the skins for each run but i just ran one with my team and they got the skin but i did not. I damaged the compiler as well with plenty of mags from the HMG so i didn't understand why I didn't get it. We exifiled around 10:15 on steam with the follow members even got the Biotoxin weapon
