Little imps have invaded RuneScape and have been stealing anything which isn't nailed down! It's mostly nothing important, but they have also stolen 4 magic beads from Wizard Mizgog, and he wants them back. Go and talk to him in the wizards tower to get started on this quest.
The trading feature has been improved further. You can no longer accept an offer at the same time as the other player is changing it. This will hopefully stop the cheating and make trading with other players safer.
A few other minor fixes have been made, for instance you can no longer walk through one of the walls in the ghost town.
