We are running into a bug(?) where certain reactions/likes are not displayed on the main activity stream. It seems to be hit and miss. At first they do show, but after a few hours they tend to dissapear, but not always it seems. These "activities" are still visible on the member profile page activities, and when I disable the "Hide IGNORED TOPICS on activity streams" setting they re-appear, so from my perspective it feels like a bug.
My account has nothing ignored, and we are getting reports from multiple members who see their own likes/reactions dissapear from the activity stream. We are running Invision Community v4.6.4 with a default theme and version 2.3.3 of the Ignore Topics plugin. The only other plugin is TapaTalk. I have full server access and I am a PHP developer, so you can ask me to look in the DB/logs/whatever. Let me know what you need to help us 🙂
