This isn't technically a bug, but the ways in which the implementation of autoplay and whatever algorithm it's using to try and pick the next video is making the site a monstrous pain in the ass.
After I finish watching videos, seemingly at random, the site will decide that it wants to autoplay another video for me. The problem is it has some kind of obsession with videos that I've already watched. A few weeks ago it was the "Apex's out now" video, then it was the Wargroove quick look, then the Dota Autochess quick look. The unifying theme? All of these are videos I have already watched. Then, unless I'm an absolute hawk (because I frequently watch videos on a second monitor while playing something like Destiny) I'll often miss the 10 second window to bail out and the next video will start up.
That's annoying enough, but thenthat video is treated as 'unwatched', so the video shows up in the 'continue watching' carousel. These days about the only way I can stand to use the site is to go directly to https://www.giantbomb.com/videos/ and pick videos one by one then instantly close the tab as soon as the video ends. I'm seriously starting to lose my mind dealing with this.
