The purchase history is definitely bugged for me. Has been since the start. I'm surprised I haven't seen more postings or mentions of this. I use that history for all my bids and posts and you currently never know if the history is accurate or not. For instance, go to an I/O recipe at level 45, see the purchase history. Then switch to same I/O at level 30 and it's exactly the same, including bids/for sales. It's as if the history is not distinguishing one level I/O from another. So you might think your level 30 I/O recipe has a going rate of 1 million influence with 50 bidders but in fact there may be no bidders for that recipe at level 30 and it only sold for 1000 influence in the past.
