Vendor Issue 3.3.5a

[senojin 2]

Hello Team, 

I play on on the wrath client 3.3.5a

My bots have issues going to the closest vendor to sell once bag are full. They always venture off and skip the vendor in the zone they are in and go to a vendor in the next zone or even next few zones. It doesnt make sense. I have shorten the search radius and this does not fix the issue. I have even black listed whole zones and it still doesnt prevent them from doing it. The crazy thing is they dont do this all the time but buts very frequite and its a big problem. 

Any insight on how to fix this would be great, at this point I think its a bug. 

Thank you.
