uSkyBlock
This DevBukkit page is being updated again with current releases and links to the maintained uSkyBlock project. We had lost access to the DevBukkit project page for some time, but have now regained it and are bringing it back up to date.
uSkyBlock is an open-source Skyblock plugin for Paper and Spigot.
Start on a small floating island, build it into something thriving, complete challenges, and team up with other players to push your island further.

Why uSkyBlock
uSkyBlock gives you a complete Skyblock foundation with island progression, deep customization, and a maintained open-source codebase you can build on long term.
Complete Skyblock gameplay. Build your server around islands, progression, challenges, and party play.
Deep customization. Shape the experience with focused configuration including challenge design, biome options, custom islands, and more.
Integrates with your server. Extend uSkyBlock through its public API and placeholder support so it fits cleanly into your server.
Open source with proven lineage. uSkyBlock is fully open source under GPLv3, free to run, and backed by more than a decade of project history.
Maintained for modern servers. Continues to evolve for current Paper and Spigot versions, with new features, docs, support, and maintenance.
International by default. Support international player communities with bundled translations into 53 languages.

So I found out what island is causing it, but not sure why. I think we found the island anyways.

Posted Feb 4, 2016So it apparently takes forever to "create" a player's island, but my console says otherwise?
Console: [16:39:54 INFO]: cj89898 issued server command: /is create [16:39:54 INFO]: [uSkyBlock] Finished creating player island.
It doesn't send the player to the island after it finishes creating.

What versions do you use might be helpful to know to start with (/usb version) and your scoreboard version.

Posted Feb 4, 2016Scoreboardstats doesn't work anymore
[ScoreboardStats] The Replacer: VaultVariables cant be registered because that plugin version isnt supported (You have an outdated version of VaultPlease update it)
Is this Vault or Scoreboardstats? If this is Vault, which one do I download because you need vault for skyblock, right...?

Any clue what player it might be? (UUID)

He thinks it might be caused by a player uuid leads to null value of player info. Nothing he can do as it might be a (player) corrupt file, but not 100% sure.
Don't think we can do much about that.

Posted there and no luck. So you believe it is an issue with passing a modded entity taking damage possibly? That's what it seems like to me. It's just annoying because it spams console and there is no way to disable it.

The tutorial video also says that when having problems contact us with all the versions of the depended plugin listed not a list of what plugins you use.
You also might want to read the page and click on "bug report".
You will find your issue explained there.

To be honest, I didn't even know KCauldron had forums :P. I'll post there. Thanks for the help!

I've put the error forward to our dev and see if he can have an answer.
As said before I've tried to setup a KCaldron server for testing but the client keeps failing me and crashes. I have a Forge 1.8 client that does work but wont connect to a 1.7.10 KCaldron server (obvious of course).
Have you tried in the KCauldron forums?

You still didnt read the bug report page or you know what to do.
I bet you an outdated plugin is the cause.
