I believe there is something wrong with forum notifications, since I did not receive any after being replied by another user in a post I am tracking. More precisely: On the enclosed screenshot, I believe there should be a notification from bspigari almost on top, but there are none from him (the latest notification of the same user is from several days ago):
Its a good question! There isn’t a “bug” here, but it’s worth explaining why
Firstly, note the bottom of your photo - you are “tracking” this topic, which means you don’t get a notify for every reply (that would be Watching)
Second, the reply isn’t to you but to the topic in general - you can tell because there’s no and avatar above the reply. So this is “just” a new post on the topic.
Finally, you aren’t named (via @) in the post. So in the absence of a specific reason to notify you, you get the Tracking behaviour.
Now, the real question is why that topic was Tracking in the first place - normally once you interact with a topic it gets moved to Watching so you do get notified. Did you change that, at all?
Ah, looks like the default is Tracking. I can probably change that for everyone, but I’ll need to do a News & Announcements post about it. Thanks for alerting me!
