Steam deleted a lot of topics last year. Mine included as I was annoyed at "STEAMS" poor support and unwillingness to fix authentication issues which made C2 unstable and prone to crashes.
I know ashley/tom comment there if you raise a concern.
But why comment there when you can comment here.
part too: game assets, I don't understand how that works, but I can already do this by dragging my assets into c2. What you ideally need as a show case that people can choose assets and the internet is full of those.
