What i wanna know is why you guys don't have a system in place to be able to disable certain npc's or certain items npc's sell. Sounds like you guys cant fix this till you patch again, this is amateur hour Bioware. L2program ffs.
People unintentionally exploiting (i.e. accidentally selling one or some such thing) is going to cause a much bigger headache than just fixing the problem.
And how am i to believe you even have systems in place to know who is and who isn't exploiting if you can't even fix the exploit in an efficient manner and you literally have to tell the community "hey don't do this, we F(*ed up but you gotta pay for it"
The rest of you thanking bioware for being open need to be more critical of how this is a small example of a much bigger problem with this dev team. Don't cut them slack, make them work for their paycheck like the rest of us.
