Posted Dec 27, 2016Hello,
I am running a Project ozone 2 server with uskyblock and i have a couple of problems:
- Exp Orbs not dropping from mobs when i use any spikes from extra utilities.
- Killer joe ( EnderIO) not attacking
I think it's because of worldguard and i have little to no experience with the plugin.
Any help would be very appreciated.
Regards,
Andy

Posted Dec 17, 2016The spawning of creepers is still MC vanilla. I think you can turn creeper damage off with WorldGuard. Same for the villagers, we don't interfere with those settings through uSkyblock.

Posted Dec 14, 2016To delete an island you need to do the command:
/usb island delete [playername]
This will delete the island and the according files/values in files.
(Plz next time don't use bold writing, I'm old but not blind )

I think it's an old island/players.yml that has names that have been changed.
Open the players.yml and delete the trusted players should fix it.
If not in the players.yml then it's in the island(X and Z).yml.

Posted Dec 5, 2016Hey dutchy, short question hope you can help me there ^^
i am getting this in my console:
[11:51:17] [Server thread/INFO]: Island 770,-2970 has invalid trustee-value
(this gets spammed there), any way to fix it without deleting the file in the uskyblock path and do i need to remove it in the worlguard regions file too ?
Thank you already, HALOween.

were did you get that version from???
In your main server folder is an other folder called "log" in there you find a log file that can be read with a text editor.
Post that through pastebin and link it here.

For the moment there i noting I can do about the spawners then the option you already said yourself. The only way is to have the spawn on a different world for now.
@H2oDragon83
Lots of challenges have been changed in the last release but I dont think the timer goes fully back yet.
EG. The cobblegen challenge will be reset to 66 cobblestone and not 64 as the original. As far I know this is a limitation out of our scope.

Posted Nov 17, 2016@dutchy1001 thanks for your help i decided to build a spawn now lol.
I wanted to place a pig spawner in my spawn but nothing spawns in the spawn area at 0,0. If i change " if true, the limits below will limit spawning enabled: true" to false it will start working however it stops the mob limits on the islands.
Is it possible for my to keep spawn limits on islands while having the spawner work at spawn?
Thanks

There is an config option "sendToSpawn: false" if this is set to true it will send you to the server spawn.
You do need a "spawn" plugin like EssentialsSpawn (addon) or simular (aslong the plugin can do the /spawn command).

Posted Nov 14, 2016Is it possible for players on death to go back to the hub or respawn on their island instead of respawning at 0,0?
