workshop worlds not showing up

[MorgnMuffin]

so every world i subscribe to doesn't show up in the game and tells me to subscribe to worlds first to use them. ive tries restarting steam, the game even my pc and it still tells me to subscribe to worlds to use them or whatever its not letting me use them, steam tells me that i subscribes to these worlds but i cant use them. I repeated alot of this but oh well

I just had this issue, turned out all I had to do to fix it is verify the integrity of the game files after I installed the worlds. Gear icon on the right in the library page. Properties -> installed files -> verify integrity of gamefiles
