sorry for that yes, some ppl at the shopping mall disconnect you if your on silabsofts client, i have no idea why they do that but they just do it
you should try going on another ccount and on moparscape client and then they should work (shops)
and after u killed daggonoth the server crashes, i have no idea why thats happening
try with full dharoks or so and no silabsoft items on moparscape client
