Posted Mar 27, 2015server version (Craftbukkit/Spigot) 1.8.0 uSkyblock version - 2.3 HF1a WorldEdit version - 6.0 WorldGuard version 6.0 Vault 1.5.3 - b37
Whenever I die, I end up on a 1x1 bedrock in the middle of nowhere. Normal users can access the GUI, but cannot create an island, or do anything with islands. I deop'd myself, and I was unable to do anything. and I'm not losing food, even though I have it on Normal. Mobs sure spawn an awful lot so I figured my food health would go down. but its not.

Try the commands /is info first to get the level calculated.
This is a known bug and will be fixed in the next update (after 2.3-HF1a)

Posted Mar 23, 2015Hello, cakes here again.
The latest version of uSkyblock has one flaw in it which is the island levels bugging. There was an error with /is top and /is level before, it's solved-ish on my server but most island levels are still not generating, thanks!
Let's hope that this wasn't a vague report.

Posted Mar 23, 2015This plugin is truly amazing and its features are outstanding.
If you're one of those beginner server owners, I'd recommend uSkyblock because it has a kind interface and easy configuration file. Dutchy, you've done an amazing job on developing/managing your plugin(s) and love your work, keep it up! - Cakes

It looks lie you have a wrong dependend plugin, I presume Vault.
Downgrade Vault to version 1.4.1
If you still have the problem after, post a log of the startup (preferable through pastebin) and the info from the command "/is version"

Posted Mar 22, 2015Hi, I have a 1.7.9 Server. My server was recently transferred to another host and some of my plugins were corrupted, when i transferred them to my new server host. (For whatever reason) I changed all the plugins that were corrupted but uSkyblock does not have a 1.7.9 download? I tried using the 1.8 Versions but when someone on my server does a challenge command it gives an error on the server and it sends me spam on console. Usually this is the most frequent error. "Caused by: java.lang.NoSuchFieldError: SLIME_BLOCK" Along with other 1.8 Blocks. On my server it gives the "An interal error occured while attemping to perform this command." Is there a way to get the 1.7.9 uSkyblock plugin that does not Contain 1.8 Blocks for the challenges? Is there a way to fix this?

we know it's working in 1.7.9/10, the other version you have to try. Using the dependencies for the 1.7.9 servers would be recommended but I cant say for sure for older versions.

Is this backwards compatible with older versions of minecraft like the old uSkyblock is?
I have 1 version of uSkyblock on my 1.7.9, 1.6.4, 1.5.2, 1.4.7 servers.

do the command /is info first, then it will recalculate the /is level. This is a know issue and will be fixed in the next update.

you should just be able to add the jar file to your plugins overwriting the old one. All should be fine then. (don't delete the uSkyblock "folder" when updating ofcourse)
@Disorbs
No that would not be the cause. This should have been fixed ages ago as it had to do with the lastisland location/the oprhan files as far I remember(not sure anymore).
Does this still hapens to you then??

Posted Mar 19, 2015just wondering if an island spawns on top of another island was it because i removed their bedrock and when a new user created an island it chose that spot as an empty spot because it had no bedrock and made one on top of another? if so fixing this problem would just mean to readd their bedrock? and if so does it have to be centered or anywhere on the island?
