Hi and thank you for letting us know about this issue. I will try to test it by making some trades of my own (1 per day) and see if the same thing happens to me. Please don't worry about it, and I will let you know when I have an update (I guess in about 2 weeks!)

Thanks for your patience, - I figured out what happened. This turns out to be related to issues we have had with the cron (the code that runs automatically every so often, and handles things that happen daily)

It seems that this failed to expire your trades for a few days, and when it finally succeeded, it expired the whole backlog at once, causing all those items to get dumped into your inventory at once. We apologize for this inconvenience. It does not seem like the issue is still happening, though we are still actively looking into other issues with the cron, so I will lock this up now. I hope this gives you some answers at least!

Please post about lag and errors on the dedicated topic :) Timeouts, Error Codes (5xx), Lag | FIRST POST UPDATED 7/22 Thanks!
