Currently, I am able to load my steam inventory and all games other than tf2 without problems on outpost. However, trying to load my TF2 inventory results in a "There was no response from the server" error, and an empty 500 response to the ajax request. This seems to be 100% reproducible for me since yesterday morning, changing browser or device doesn't help.

I'm considering this a site bug rather than a steam one currently, as I seem to be consistenly running into this problem on outpost, but have no issues loading my inventory on other sites I have tried. The steam web api also seems to be working correctly when I tested it after running into this problem.

I have a feeling it might be something to do with the number of items in my backpack, as I've never had this issue prior to yesterday, which was shortly after I completed a large trade and reached 1900 items.
