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.

I have no experience with the plugin "MyCommand" but I do think that it is because their custom made commands.
I've had a discussion before about this a good while back and I think due to the way it's coded for some reason it will not accept those commands. Dont ask me why as I cant remember that anymore.
I also dont know if this can be changed or fixed, but maybe a dev from the team can answer that.

This does not sound like an USB problem. Is it only you or does your players have the same issue?

I'm sorry you feel like your a guinea pig. I been pushing for a new release but when testing (I'm the main guinea pig) there are other issue's poppin up that has to be fixed before we can release a new version. There has been a good few pre-releases on our github but none of them are good for a public release. As I'm not the one that codes I'm depended on our team. We do have some great contributions from our new member Harry5573 which helped a lot. I do think now the school holidays are over we will hopefully get some more work done but I cant promise anything.

Posted Sep 1, 2015Can you guys make a new, stable release? We are still on HF3, which is over three months old, and I'd like to install a new version without being a guinea pig for bug testing.

This is because you are OP and will have all the permissions.
When OP you need to either negate them for yourself (and/or other OP members) or deOP yourself when completing a challenge (but as OP you deserve the extra bonus ;) )
I've added the "bonus" permissions to the "Command & Permissions" page.
These permissions can be used to give, for example, donors an extra reward when they complete a challenge. All together these bonuses give 50% but given separate you can choose what they get.
