If it was easy to do and took little effort, I'd give you a list of all my add-ons.
1. Open Blockland, start a game.
2. Once the server starts, immediately open the console and type trace(1);
3. Once you've spawned, load the events and get them to give you the same error.
4. Close Blockland.
5. Open the folder that contains your console log. This is either in C:\Program Files\Blockland or C:\Blockland
6. Attach console.log to a post in this topic.
That wasn't so hard now, was it?
