Nobody has reported any issues. Try to look again - I’m sure there is simple explanation similar to previous one. Re-check notification settings for particular topics.
For me to investigate I need to know which topic or need to have that email resend to admin@overgrow.com.
Also check out your preferences in profile.
Also please mind how different notifications settings work. There is difference between Watched topic and Tracked topic. Watched topics send notifications and also show post count next to the title. Tracked topics only show post count (and you’ll be pinged/notified only when someone mentions your name).
