    They changed how the chunk queue functions in build 3022 which causes the server to crash if you have the chunks feature in nolagg enabled.

    Confirmed, i am experiencing this too

    Full server crash report http://pastebin.com/1YyJkP3v

    After removing nolagg, the error was gone

    You don't really need to remove the whole plugin to get rid of the crash, you just need to disable the nolagg chunks section of the plugin, as it's that that is causing the crash.

    Also another temporary workaround, if you want to run with nolagg chunks enabled, would be to downgrade to CB3020 as this build is stable with nolagg chunks. As it looks like you're running the spigot server from the crash report, you would have to downgrade to a build that doesn't include the commit in CB3022 for that to work.

    Oh thanks! That fixed it indeed
