I would like to let you all know that we have made the decision to convert to spigot, running a semi-vanilla server instead of a vanilla server. Vanilla may make a return in the future. These changes mean that we will run a spigot jar and will run plugins instead of using command blocks/functions. We weighed both sides and decided that semi-vanilla will be a turn in the right direction for the future of YourWorldMC. We would like to apologise to anyone who may not like this change.
THIS WILL NOT HAPPEN UNTIL 1.13
