Certain episodes/movies infinitely loading after pressing play

Certain episodes/movies infinitely load after selecting them/playing them.
Some episodes/movies eventually load, some don't.

Can you list the ones you are having issue with?

So far I've only encountered this issue with Gravity Falls S2E21.
It seems it can't find any streams for that specific episode (there are no streams listed in the console as well 🤔).
