Crash on connection

[Jagthelad]

So I used the /i command to spawn an item but I messed up the item ID and spawned the wrong item. It appears that whatever I did spawn is horribly corrupted and definitely does not want to be spawned in because I now crash on connection to the server. This is on the DW20 1.7 server

Just to add, the error I get is: 

The game crashed whilst rendering item
Error: java.lang.ArrayIndexOutOfBoundsException: 3

Moved to DW 1.7 technical support
