Your haven't stated if your patched up for ServUO to the lastest or? If not up to the newest servuo have you changed vendors at all?
I can tell you if so, then staff runebook and the toolbar were removed as they were custom scripts

Thanks for the help Milva but I haven't touched my version of ServUO. So no, I haven't patched. It just seems like some scripts I try to implement always have the same problem. The staff runebook doesn't work and the vendors don't respond.
