bazaar endpoint's sellVolume/buyVolume is very wrong

[csjh]

The value for sellVolume (and buyVolume, but to a lesser degree), which the docs say is the "sum of item amounts in all orders", is off by a significant amount. Here is a list of the items I found were off (this is only items with less than 30 sell orders, since I can't manually count the amounts outside of that). It shows the disparity between the api's value for how many items are in buy orders vs. how many are actually in the buy orders. The list is formatted product_id | api_amount - actual_amount | api_amount / actual_amount

These numbers range from being spot on (in the case of ENCHANTED_PRISMARINE_SHARD, ENCHANTED_RAW_CHICKEN, FLAWLESS_RUBY_GEM, ENCHANTED_PRISMARINE_CRYSTALS, and ENCHANTED_FIREWORK_ROCKET), to as high as off by a factor of 132.88x, in the case of FINE_JASPER_GEM.

As previously mentioned, the problem is also present in buyVolume, but to a much lesser degree.

It might be the case that this is an issue with the in-game bazaar data actually - who should I contact about that?

The data does indeed come directly from the SkyBlock Bazaar service, so if there are any issues it's a game bug rather than the API as the game uses the same data provided. You can create a bug report here to report it, thanks!
