The Excavator?

So I finally got into a few Halo 3 games today. I checked the carnage report after one of them, and this is what I saw.

I know there are plenty of more pressing issues with the Halo collection, but how did they get two weapon names completely wrong? I’m not even mad, I’m just stunned.

Is someone at 343 trolling?

Okay, now that is just hilarious.
