No World Selection?

So I know this can be a lag issue, but I'm getting it for no reason. I'm not lagging, everything is perfectly fine. The game was running fine just hours before this, and now, for some reason, I cannot see the worlds in the world selection. Is there any solution to this or am I just forbidden from doing 2x?

EDIT: I did restart my computer. Nothing. But I did launch from the file client rather than the Steam client and it worked.
