I figured this was a known issue and would be sorted out in time, but it's been happening since the site update many months ago, and after a search for recent topics about it I couldn't find one, so I suppose I'll make a topic for it. After a certain amount of time, alerts no longer show up, both as the red number signifying alerts are present, as well as under the Alert tab itself (if I manually go look, they're not listed in there either.) However if I go to my Watched Threads, I see multiple updates to topics I'm following, some extremely recent, and certainly since I last hopped on and off the site. To remedy this, I have to go into the topics I'm following, and Like or Unlike someone's post, and then suddenly the alerts begin showing up again (including for the topic I just Liked or Unliked a post in.) I've been manually going to my watched threads and doing this daily or semi-daily to address this, but then inevitably, the alerts stop displaying again, sometimes within an hour or less of resolving the problem, but usually after a longer period. I've seen other users mention this happening as well, so I still assume it's a known issue, but since I couldn't find a topic for it, I figured I'd make one since I know I'm not alone. Sometimes I completely forget a topic exists without the alerts until I check my Watched Threads, and I've tried winnowing down my Watched Threads but this doesn't seem to resolve it either. Consider this more an inquiry than a complaint or criticism. Just wondering what's up lol. I love everything else about the site update.
