Works well, sometimes throws the error. Thanks

Throws an error in console:
POST https://steamcommunity.com/id/******/ajaxactivateconsumable/ 400 (Bad Request)

@Rosenstein: It throws an error because of this: item_type: 127, (there are much more item-types) The error could happen anyway for different reasons -> like to fast requests in a row, also might be known as spam. Sometimes success: 16 and a 400 HTTP-Error gets thrown, but if we try it again, the item is consumable. So no idea why this error occurs, some special people would call it "Steam Fuckup". You can find a different fork out there that actually works (better).

Thanks for your work
