Did something what Steam didn't, told devs about a new required graphical asset for games on Steam.

Hey companies, if you require something new from your customers (from game devs in this case), make sure to communicate this. I'm tired of finding random stuff like this after months, it's painful.
Or hire me to be the person documenting this kind of stuff.
