same thing happened to me at 9. Ihave reported it twice but no acknowledgement of the tickets even tho they gave me numbers and they dont show upo as open tickets. I have had to leave alchemy for the time being. Not fixed in this patch either.
Thats easy to beat, every time someone posts an out of range bid the ah can either dissallow or add multiple copies of the bid so you have ony, say, one chance in ten of getting the right one. That in itself makes it 10 times harder for botters
