Incompatible plugins / mods

Please note the following plugins / mods can cause issues with HuskSync:

• Restart plugins / mods are not supported. These will cause player data to not save correctly when your server restarts due to the way these plugins utilise bash scripts. It's important to understand that restart plugins don't actually restart yur server, they just trigger some (often unstable) process-killing scripting logic to occur!
• Combat logging plugins / mods are not supported. Some have built-in support for HuskSync and should work as expected, but for others you may wish to modify the Event Priorities
