People have reported a few issues with Statz 1.3 and so I've worked on fixes for these! I represent the bugfixes:

• Fix errors when NuVotifier was not installed on the server.
• Fix stacktrace when log manager was not initiated properly and Statz tried to write to a log file.
• Added an option to enable/disable debug messages in the console (see config.yml)
• Fix Statz not storing when a player killed a 'killer bunny'.
• Fixed error when Jobs Reborn v3.5.7 was installed. Due to a change in files in Jobs Reborn, Statz 1.3.1 only supports 3.5.7 and higher. If you're running Jobs Reborn, make sure to update!

When you find any other bugs or errors, please report them on the bug tracker!
