My lich was stabbed by another player causing it to rank up without a code guess

[GovernmentSecrets.gov]

I joined an Interception lich mission on Earth that was already in progress, and after we dealt with a lich that was already up when I joined, my lich spawned. When my lich was downed another player was able to execute it triggering a rank up as if I were the one to have done it. No previous code guess was logged in the lich screen after this occurred. 

I do have an F6 screenshot of the lich screen taken while I was in the mission this occurred in.

If it's relevant...why not include the screenshot in your post?

I don't see a way to attach it here without uploading it to an image host such as Imgur which would remove the metadata embedded in it. Plus it's not really a map hole or anything, so it's more likely than not redundant.
