Hello

I wonder if its possible to blacklist vendors, or even cities, because my bot tried to enter a city where its only entrance is a lift, so its impossible for the bot to get inside.

So can i blacklist the vendors, or maybe add a main npc the bot always will go and sell to?

You can blacklist vendors (tools => blacklist), remove them from your profile (if that's the source).

You cannot set a main vendor, but you can set your profile to ONLY use vendors from your profile, not your Bot's database.

In a quester profile, it looks like this:

<QuestsSorted Action="RunCode" NameClass="wManager.Wow.Helpers.NpcDB.AcceptOnlyProfileNpc = true;" />
