He's asking whether or not he will win the items after the auction ended if he has the winning bid.
Example:
I am level 85, In the auction I can see level 101 with praetor I think. I bid on level 101 ring, or whatever, and nobody else bids on that ring. My seal of praetor runs out before the auction runs out. So do I still win win the ring even though I can not see it in the auction anymore? But my bid was the highest bid..
I dont know the answer to this, but I would definitely like to know.
I think that you would still get the item even though you were no longer able to see it, the only problem i can see is that i don't think you would be able to wear the item on your main character. Only a merc because if you no longer could see 2 items higher.... i dont think you could use them either
