Exterminations only work on Overkills!

So, 343 finally listened and made Exterminations work (as far as I can tell they work in Custom games), with the exception that they don’t work with high multi-kills. They ONLY work on Overkills. This means that if you “wipe an enemy team with AT LEAST an Overkill,” like the description says, it only works ON the Overkill. You cant get the wipe on, say, a Killtrocity and have it awarded. If you can fix that 343, it’ll work how it’s supposed to. Please update the medal to work how it should!
