Not sure what usb version you use but the we are working on this.
@ShadowDragon7015
A detailed explanation what every line in the config does is listed in the Challenges page to be found on top of this page (not sure how you missed that).
As I do not use Pex but GroupManager (GM) I have tested your custom challenge on our test server and changed only the command from Pex to GM and deleted the
line displayItem: PAPER as this will not be displayed in islandLevel challenges.
Example with use of GM:
The command line has move under the "tag" commands: as shown above. You have to change the GM command to Pex and if I'n correct like this:

Posted Aug 2, 2015I seem to be having a bit of trouble with the plugin. Whenever i put a command for the challenges to run it doesnt run the command at all. there are no tutorials showing how to use that part of the challenges so i am completely stumped on what format to use for the challenge: what i have right now is this: skylordtitle: description: 'Get an island level of 1000.' type: islandLevel requiredItems: '1000' displayItem: PAPER reward: text: 'Skylord Title' commands: 'pex user {player} suffix &1Sky&fLord>' and it does not run the command when the player completes the challenge. please help.

Alrighty aha, just thought I should ask. I'm really happy y'all are adding the /trust command! Pretty excited for when the reduced lag features are implemented also, I'm sure the members on my server will be happy also.

As i'm not the one that codes it's hard to tell. I know 1 is on his holidays but will be back after this weekend. If his kids let him play is then the next question, lol.
The latest pre-release is only a few bugs away which been introduced when an other one was fixed, as soon this is done we will release v2.4.
Few of the fixes so far:
Added a /trust command so players can help out whitout being a party member

Thank for responding! I'm just relieved its not my server. I was hoping it wasn't just the server cause I genuinely don't feel like upgrading. I tried a pre-release before and it messed up the skyblock world so I reverted back to a stable release. I like to wait until a stable release is put out before I update but thank you for the recommendation! I'm glad to see uSkyBlock has a dev thats working hard to get new versions put out. (=
Would you happen to have an estimate on when you think yall will have a steady release? If you have no clue its fine, I just thought I should ask.

We are aware of this and are working to fix this issue. Depending on the versions you use some of the later pre-releases are showing improvement. As were still not totally happy with the end result (also due to some other bugs) we havent brought out an official release yet (but we aint far off now).
Pre-releases are only on our Github page and use of them is at server owners own responsibility (always backup before using/changing a plugin is recommended).

Posted Jul 31, 2015Whenever a player restarts their island the server gets a HUGE lag spike. It's starting to ruin the server with all the lag that goes on. I have a 6 GB server that has 1.5GB dedicated to plugins and 4.5GB dedicated to the server. The islands are only 250x250 I don't feel as if the islands restarting should be lagging the server.. Is there a reason it lags the hell out of my server?

Doing the command /usb island protectall should not give you any problems, maybe some lag while this process is running depending on the amount that has to be protected (32.500 took just over 3 hours).
If you know what island it is you can also do the command /usb island protect [playername].
I presume this can be a WG but not sure why this is happening, it can be something to do with "nicknames" but that is not confirmed yet.
Backing up the folder(s) is always a good idea if your trying to do something, I suggest this for any plugin (better save then sorry, you can always delete a backup but never get lost data back).

The versions you use are fine.
You say "I deleted my oldest version of skyblock..." What you mean with this? Do you have multiple versions of the uSkyblock.jar in your plugin list?
Can you post a full log file from startup so I have a better look what is going on?

Posted Jul 28, 2015Thank you for the quick reply. I was kinda basing my donation system off of this, perhaps i should have done my research a little better before starting. Thank you though

To have different islands for donors is done through schematics and permissions, but this is what you already know.
In our upcomming release we have added a new feature /trust which allows you to be member for multiple islands without being in the party system or losing your own island (if you think outside the box you get a long way).
I dont now any other plugin that will allow multiple islands but I know a server were they change some of the WG region files manual to give access to multiple islands (I cant recommend this).

Posted Jul 28, 2015Hello, i was wondering if there was a possibility to add multiple islands onto one class. i've looked all over the internet and i have seen people mentioning that there were ways to make more then one island. and i mean more then one island, not just a schematic with more then one island. i have seen other servers that offer more then one island for donator classes. if this plugin cannot support that does anyone know of one that does? I would appreciate any help i can get with this. Thank you.

This is due that the schematic is saved while not standing on it. If you select it againn using WE but stand on the island it should be ok then (remember to swap the file from the WE folder to the uSkyblock folder then).
If this doesnt solve it let me know were you got the island from or get it to me through for example mega.

Posted Jul 28, 2015Thanks for the plugin it's amazing but How do I get the schematics to work I downloaded a island from a website for a skyblock island and put it in my schematics, I restarted the server and it spawned in but I didn't spawn on the island but by it.

Read the section above "How to report an issue or bug"
The log file only gives warnings, not errors. The log also gives warnings on a few other plugins. This tells me that there might be something else at fault.
