Whenever I execute "/skyblock play" the following appears in the log:

Player <Name> is executing command "/skyblock play" in world "skyblock" at world age 985.

I added the "World=skyblock" and "Plugin=SkyBlock" to settings.ini. I am able to join the world, which puts me into an empty world without any platform.

When accomplishing the "fisherman" challenge, both first and second time at least, the challenge will not claim the full cost from the player's inventory.

It would be cool to make a skyblock island that players can play on in the nether. Once a player can build a portal, they can build a "hellblock island" and earn other achievement in the nether. Also roll items from nether into the skyblock dimension for more advanced challenges

The "lumberjack" challenge calls for 16 of each log type, however, will only take one of each.

There have been multiple complaints on the Equitas skyblock server stating that players are not getting the awards for completing a challenge. I have had this happen to me as well. Not sure if the issue is a plugin conflict, or a Cuberite issue. But since this is the pack that players notice the issue in...

I can't remember all of the commands, but the /skyblock help and /sb help commands do not work, they simply return an error. However the other basic commands do work.

It would also be cool to at some really advanced point, allow players to place and spawn an end portal, which will allow them to build a "Endblock Island" that features end based challenges, with rollover from hell and sky for more advanced challenges, then overall, require both hellblock and endblock items for supreme challenges.
