If the log is outputted to the console, all animal kills are not included.  Can we get a quick fix for this and maybe some promised updates from 7 months ago?

Do you mean logs of kills or actual killing of animals? Because both are not something this would manage. If you are requesting a feature be added, that is not a fix, just an additional feature. I am not aware of any other issues either, only feature requests.

"So-And-So killed a bear"... this was something the console has always shown, yet when implementing this plugin, it no longer appears when players kill animals.

Sorry, but that isn't possible, as this plugin has no interaction or relation to logging death messages.

Has the console by itself without any logging plugins ever spat out something that said a player killed an animal?  I could have sworn it did, but now it's just not doing it.

The plugin hasn't ever, you can in the source so see there is nothing related to that. Death Notes may have? I'm not sure if the game ever has natively.
