Every time i do /newisland replace Its the same island but cleared from what i placed and their still a bridge from some1 else's island And i'm hoping a Admin or mod should help me. ** By the way the mods on the chat Suck at their job helping :/**

 

Saying 'You suck at your job' then asking for help is probably not the best way of asking, though you did the right thing and made a post on the forums.

When you do /newisland replace it will only remove blocks within 49 blocks or your bedrock spawn. Since the bridge is starting from another island, what remains will be within their 49 blocks.
