This has been happening a few times and i can't find anything on it on the internets. Here's the story:
I want a String of Ears pretty badly. I'm a monk stuck on act2 inferno and it would help me immensely. So yesterday i booted up the auction house, and took a peek. Obviously the lowest buyout for the worst versions are 500-600k gold, and i never had more than 400k(don't like the idea of farming), so i looked at the bid prices and found a few very cheap ones that are actually pretty good in comparison, and i bid on them(4 pieces from 25k to 100k). A few bids i lost in a matter of hours to buyouts and people bidding over a million on them, until there is only one left. And then i start a bidding war against a guy(i assume).
So half an hour ago i boot up the game again to see how i'm doing. There's still a few hours left and i still can go about 70k over the price that i last put in. According to the interface i were overbid by 10k and got my money back. So obviously i jump back in, bid the amount that the computer offers. My money gets rejected automatically saying there's a higher bid. So i go back in, and put in my own number, a number rounded to the tousands. The computer refuses, saying there's another bid higher, and shows a very oddly rounded number compared to mine. And this goes on and on for 4 times. Right now i'm at the point where i can't bid no more i have no money left.
I don't know if this is a glitch or the auction house itself keeping the prices up artificially, but it's very strange. This has happened before too. if i enter the number 1274 as a bid the current bid goes up to say 1428 and there's nothing to that, it's just weird numbers, i mean it could be a desync issue. But if i put in 1000 it gives me 1250 as the current bid then i enter 1500 and it gives me 1750 as the current bid, not accepting my bid on it, it's a little strange.
The only way i could break out of this cycle is to bid way over the price that was listed as the current price in my interface, like it listed 1500 as the minimum buyin and i went 2500 suddenly.
Is this just weird desync, or is blizzard haing the prices kept up by bots?
Edit: tried it again, still trolling me. Put in 300k it came up with the price 315k. It just seems the winning bids are always whatever i bid+5%
