We have a bug list? And this isn't on it? It's been an issue for as long as we've these discussion pages
Well, when I said bug list, I meant...this. I didn't know this issue was so old, but I wasn't able to find a topic on it.
"In distress", my ass.
You don't even need to leave the page when you reset the watch, just remove then add the watch.
That said, it's been an issue for quite a while, but as I understand it a rather lower priority one for the sole coder for this site.
I've missed more than a few discussions until long after it had gone quiet because of that... 
Previous topic on the same thing
. And I think it had been mentioned in Ask The Tropers before that, which is how I knew to check. So the issue is at least over a year old.
Hi
Bumping to verify whether or not this is still an issue.
Seems like no, so closing.

I've found that quite a few pages I have on my watchlist do not also have the corresponding discussion pages watched. There's an easy fix (just de-watch the page, navigate to another page, navigate back, and re-watch it), but it doesn't help much because there's no warning until someone references the discussion page in an edit reason. I almost got into an edit war because I didn't realize an example had been decided on elsewhere.
I know some other tropers have had this problem, so I think it's time to officially put it on the bug list.
