So, seems like humble bundle lied in their january bundle

Wierd.

Wouldn't be the first time, humble lied about contents of their monthly bundle xD If you point it out to them, they'll probably allow you a refund if you want

true.. missing 'Project CARS - Limited Edition Upgrade' in order for it to be 'digital edition'.. ¯\_(ツ)_/¯

Did they not provide a digital version of the game? And there is nothing called "digital edition" on the Steam store page for Project Cars that I see, so if the regular version is not the digital edition then what is?

Also, if you didn't even know what you were getting in the bundle then the implication that they deceived you is certainly a stretch. A typo or error? Okay. Deception? Umm no.

It should be Digital Edition
