Full Credits not Rewarded

Good Afternoon,

Recently, after playing game after game of this addictive server, I've noticed a few discrepancies with the credit system. There have been numerous times where I have not been rewarded credits for kills (and only kills, I have not noticed this issue with other ways of gaining credits). It is usually a minimal amount, so if I had 28 kills, I would get only 26 kills worth of credits (52). I have reported it to NomNuggetNom and he suggested that I make this forum post, and thus here it is. Please get to the bottom of this, because credits are my life blood.

Thanks,
Pear915

Edit:
Here is a screenshot from a previous game. Notice how in comparison to the scoreboard, I am credited for an extra kill and credits for a recovery are missing (this is the first time I've both of these things).

The additional points for the kill may come from a ninja. I hit him (or her) and he or she died of fire. I was credited for the points in the chat but the scoreboard didn't update and I didn't get the kill message.
