You can view recent topics by a specific user by visiting their user profile page. Besides that you could or the users in a group and visit the group page.
Those are the only options afaik
If the user received a notice from the topic which deleted, he can not go through it.
Well no, it's been deleted. I thought it removed the notification tbh.
We don't store a reference of tids to their respective notifications, so we don't really know which ones point to topics that have since been deleted
@julian I saw this problem in a dream, but never really thought about it. It's funny.
Even I don't dream of NodeBB!
I don't know if I should be scared or not.
