Read morePossibly off-topic: I have no idea if it's remotely related (and I'd assume not, as this issue has occurred for multiple leagues) to the old API functionality or the recent improvements, but I frequently will encounter "quiet" sections of time for a few hours where no one messages me for anything despite normally getting messages every few minutes (I price stuff fairly low to sell a lot quickly).
I'm well aware this is silly anecdotal evidence, but the weird thing is that if I update my listed items' prices to a new value, I'll suddenly get a flood of trades for the original price I had up, as if my item just popped up and dinged a bunch of people's live searches. I'm not the only one hitting this either; other players are also seeing this bizarre behavior.
I work in QA at a game dev, so I understand how frustrating digging into this ki...
It would be useful to first determine which trade site the buyers are using as it won't be API related.
Any chance of a post mortem?
It's not very interesting; we switched to a new method of comparing items to speed up processing the API, which meant that old items didn't match when we went to mark them for deletion. There was around a 18 hour window where this occurred before a fix for comparing old items to new was added.
There was a glitch in the API exactly a week ago and a lot of sold items are still listed, it makes trading a lot more difficult. You can filter by items listed less than 3 days or less than 1 day ago.
I'm hoping GGG is coming with a fix for this because I and I'm sure a lot of people have been getting spammed for items sold a long time ago.
The fix is being applied as we speak, it should be done in an hour or so in the next few hours!
EDIT: If you're reading this and your items are still listed feel free to PM me a search URL to them and I'll investigate.
EDIT#2: It's running slower than expected, so might take a little more time than initially estimated.
EDIT#3: It completed overnight, but it looks like some items that used to be in map stashes are still hanging around. I'm fixing them up now too.
