it could be that he was giving you manual admin, then the welcome message was there to trick people?
Try moving your add-ons folder out of your Blockland folder, and then try joining a server. If it works, that means that it's an add-on.
This looks like the work of a client add-on breaking the command it receives to tell it that it is an admin.Might I ask you to start Blockland, get ready to start a server (as few server add-ons as possible), open your console and enter in:Code: [Select]trace(1);then start the server. Once you have connected and it says you're an admin, exit the game and post your console.log. This is the quickest way to identify which add-on causes problems.
