    Hey there,
    I have a frustrating problem itching its way up my nerves.

    So, I have made this Domination plugin. It works great just as it should, people on the server love it and all. But there is a bug that I can't track down (believe me when I say I have tried). What happens is that the console gets spammed with ExceptionWorldConflict errors, which make the server lag...big-time. There is a short stacktrace, but it's all NMS, nothing from my plugin.

    I have a few ideas of what might cause these errors:

    First, it's the anti-lag system which basically just removes entities from the world once every minute. I don't see how this would cause the errors, but hey, it is related to world editing.

    Then, it's the removal of arrows once they hit a player or a block. This just removes any arrow from the world on hit. I have reason to believe this COULD be connected to the problem, as I have had some troubles with this before. But don't take my word for it, as I have no clue as to whether it is as I believe.

    Lastly, and I think the biggest of them all. It's the system that creates a new world from a template once a game begins, and deletes it once the game ends, ultimately creating a new world and repeating. I don't think I have to go into much detail as to why I believe this is a factor.

    If anyone at all here has any idea whatsoever about what could be the cause of these errors, please let me know and I'll be very much obliged! ( chasechocolate xTrollxDudex CubieX TheGreenGamerHD Minecrell dumptruckman )

    Kind regards,

    I think it's fixed. Thanks to Minecrell and my intuition we came to a possible solution. I'll run the server for a few days and mark this as solved for the time being. If the problem persists, I'll reply to this thread.
