What are UUIDs?

Mojang started creating a way to let players change their username. To allow this, each player now connects to servers using their name and their UUID which stands for Universely Unique Identifier. Each account is associated to 1 UUID and it will never change. This means that servers, when saving data, need to now save by UUID instead of saving by Username. This is to prevent players from losing their plots if they decide to change username.

What do I do if it doesn't work on my server?

Well, it's probably a problem on your side. While you figure it out, you can downgrade to v0.13b without any issue. The database will still work and it will use the same plots.

Help people can't build!

This will happen if your server is in offline mode. Rollback to v0.13b or put your server online.

v0.13f

Fixes

• Nullpointerexception on player login
• Nullpointerexception when looking at a plot information on a currency plot world

This version might work on some versions of 1.7.5, but it was only tested on 1.7.9. Use at your own risk on 1.7.5.
Will not work on version below 1.7.5 as it relies on new bukkit functions that provide UUIDs.
