Charger Bug

I have charged at players dozens of times (even at close proximities) and not once have I killed them with one charge (even if I manage to hit them immediately after charging at them). Most of the time you just knock them back far away, so even if this is a bug, it doesn't happen that regularly that it should be concerned about. Besides, humans are already incredibly overpowered, so having a zombie that can one-shot humans doesn't sound that bad of an idea in the first place.
