I'm trying to override public override void VendorBuy in the vendor npc script. I can override it in BaseVendor and it works. However when I tried to override it in the NPC script it failed. Here is the override code as well as the error. Note, it DOES compile, the error appears in the console after i try adding the vendor.
Any suggestions on working around this would be great. Also, without the override in the NPC script, they do add successfully.

Code:
public override void VendorBuy(Mobile from)
{
RaceWarFactionsXML RaceXML = (RaceWarFactionsXML)XmlAttach.FindAttachment(from, typeof(RaceWarFactionsXML));
if (RaceXML != null)
{
if (this is UndineRaceVendor)
{
if (RaceXML.SubRaceXML != SubRaceXML.Undine)
{
Say(true, "I refuse to help our sworn enemy...");
return;
}
}
}
}Error:
