Here's a little problem I found:

When a user ("A" user) publish something, it appears on his own newsfeed and on their newsfeeds' friends. But if a friend ("B" user) likes or comments the original post, written by the "A" user, then the author avatar changes to "B" user, so it is tricky, it seems like the original author of the post was "B" user and not "A" user...

Hopping that it will be fixed.

Thanks!!!!
