Oh okay that's funny I see now what the problem was. The thing is, I had the videos disabled because they used to be super laggy for me. Didn't really think about turning them back on because I couldn't remember that it was something I actually did, I thought the dev had disabled them because they were so buggy. But apparently I misremembered, so I turned the videos on, and they weren't laggy at all anymore for me like they used to be and yeah, then your suggestion obviously worked.
Still a bug though for when people have the videos disabled.
