It seems like its a bug that displaying overkill damage on my nameplate makes it so the damage number looks horrendous. It would display the damage as "5.1M (0: 5060874) for example.

Hopefuly you can fix it as that is the only dealbreaker is not knowing how much I killed someone for and I don't want to disable this feature because the damage numbers abruptly go away because its based on nameplates.

What is the expected display that you are looking for?
