It would be very helpful if CraftConomy3 could be reloaded with PlugMan (via /plugman reload CraftConomy3). I've tried, but the plugin fails to load again with the error message: "Plugin already initialized." As you probably know, this usually happens due to incorrect use of statics or references to the loaded plugin that don't get changed when it reloads.

I have a command called /craftconomy reload, it should do the job you want.
