  1. Hi!

    One day I started my Server and some users began to have this error:

    Code (Text):

    Result of this is, that they cannot see the world anymore.
    There is a possibility, that this bug comes from my own plugin. But there is no way for me to see when this happens. It is absolutely random. What can I do?
     
  2. What version of Spigot are you running? Do /version
