What Spigot version does the current plugin version support?

ProjectKorra Core v1.8.8 is compatible with Spigot 1.13.2 at the moment.

How can I report a bug?

ProjectKorra Core bugs can be reported here.

As of ProjectKorra Core v1.5.0, there is a debug feature built into the plugin. This will help us a ton when you submit a bug report if you include the debug.txt created when you use the /bending debug command in addition to a log of your console if it shows a visible error. Debug will help us by listing ProjectKorra plugins and dependencies so that we can isolate the source of the problem. This speeds up the bug fixing process A LOT.
