Ah, this is just great, YT's back to somehow keeping the vids you watch from being archived in browser history again. I hate when that happens - sometimes, there's really no reason for me to actually login to my accounts, so I just watch vids as a guest, and if I want to see a specific one again, I just pull up my history and click on it (the way their search results are, sometimes you'd be hard-pressed to find it again), but for some reason, YT somehow keeps vids from being archived in browser history from time to time, and this is apparently another one of those times.
