Bug: /api/item_orders for “buy” always returns 0 for the range.
Whoops, tracked down the bug some people were reporting that all of the ranges for buy orders in the API were zero. That wasn’t literally true, but there was a bug that caused all new data (from the last few weeks) that was uploaded to have the range on the buy orders entered into the database as zero. I fixed the bug, but unfortunately all the bad data is still there, that will probably take a few weeks to clear out. Sorry about that!
