Hello, I get following stacktrace when trying to warn a player: http://pastebin.com/yFmWnfPk
I'm on latest version from BukkitDev.
Everything else seems to work.

Probably just final String reason = CommandUtils.getReason(2, args); to getReason(1, args);

Temporary fix: /warn Player . Reason, to make sure that array[2] contains the reason.

Thanks, quick question, is it safe to reload BanManager with a plugin manager like PlugMan?

As of v5.3.0 it should be perfectly fine, yes

Worked perfectly, thank you!
