[Bug; Forum] Sub-Forum Mute Missing/Disabled

Before today, the "Gear" icon to the top right of each sub-forum allowed users to "Mute" specific forums from showing up in the "Discussion" tab, thereby personalizing their forum experience. However, it seems that feature does not seem to be working anymore.

I hope this is just a bug, and the feature has not been removed without a substitute.

Cheers.

I saw this as well and am missing this feature very much. I am always using the "Discussions" main tab to get the newest messages from the whole forum (especially useful for the small german forum) and muted the few forums I am never interested in. Now messages from these once muted forums come up and clutter my "Discussions" view, which is much less useful this way.
