As designed Watched thread icon appears when threads within a watched forum appears in the New Posts section

[JulianD]

How to reproduce it:

1) Watch a forum
2) Go to New Posts and look for a thread within the forum you're watching
3) The glasses icon appears in the thread list

This is as designed. Since you're watching the forum, you are effectively watching the thread. It's designed to make the ones that you're watching stand out more.

Thank you mike.

It is a little confusing to me because I see threads with the watched icon which I've never watched before, so I thought on reporting it.
