You have to make sure that the member has the right permissions to be able to use them. They need the perm "usb.lock" to lock and unlock the island or "usb.extra.addwarp" to toggle on/off the warp feature etc etc.

Posted Apr 5, 2015Hello, I was wondering If its possible to own a island and be part of one at the same time or the ability to own more than 1 island? If not would this be included in one of your furture updates? I would love to see this be added :).

I know what your saying and have seen it a good while back too, going to spawn and back or relog will fix that.
Were not sure if this is caused by USB or Minecraft itself. As you said it hard to reproduce and happens only very occasionally.

Posted Apr 5, 2015Hey, I too sometimes find the issue where the blocks are invisible and you cannot move when a island is created. It's hard to replicate because it is not constant. I think it happens more often when the chunks are loaded by a player being in the area before the island is created. We are using the default island and here is our version:
09:15:25 INFO: Name: uSkyBlock
09:15:25 INFO: Version: 2.3-HF1a
09:15:25 INFO: Description: Ultimate SkyBlock v2.3-HF1a-2e2dfe-dev
09:15:25 INFO: Server: CraftBukkit git-Spigot-c5492f8-cf5a502 (MC: 1.8)
09:15:25 INFO: Name: Vault
09:15:25 INFO: Version: 1.5.3-b37
09:15:25 INFO: Name: WorldEdit
09:15:25 INFO: Version: 6.0;3342-78f975b9
09:15:25 INFO: Name: WorldGuard
09:15:25 INFO: Version: 6.0.0-beta-05.1569-
The problem is resolved when the all players leave the area and the chunks unload. I would like to add a delay between the island creation and the player teleport to test if this helps.

your file versions seems to be ok.
It might be because your on 1.7.xx but not sure as I havent played/tested for a while now with 1.7
I recommend to update to 1.8 but I know a few can't or dont know how too compile the new spigot.
If so I can help with that if needed (but limited with time)

that is ment to happen.
In the config you can set it to keep Enderchest, Armor and Inventories (each has their own setting).

Posted Apr 4, 2015not sure if this is meant to happen but whenever someone starts a new island they lose everything in their ender chest and in their inventory, is this a bug or is it meant to happen?

At the moment there is no option to change the colors of the messages. Our team is working on getting the language system added to the plugin, maybe we can add an option then to have custom colors too but I cant promise any yet.

if you follow the guideline here it should go fine.
It's a normal Nether, you wont get islands there.
