Totally, no errors on console log. And this is not exactly black screen, there is "loading" icon on the center, but it's loading forever. Also in main menu there is only menu visible, no background render (that bench and windows). Looks like...it can't be rendered? I dunno. Funny is that when I delete that object I placed earlier, everything works again.
Dear Justin, I wanted to say... It works today. I tried to check it again today to see whats wrong, I did nothing, executed test play, and...it works O_O I have no idea why id did not worked and why works now, but looks like it's my PC fault. Sorry for taking your time!
