Well, this is weird. I changed the favicon for a game I moderate (STATUS: INSANE https://www.speedrun.com/STATUS_INSANE), and it changed it... but not on the pages favicon - it changed only in the gamelist that is shown on profile.

I thought it had something to do with cache issues, so tried to force refresh bypassing cache, to no avail. I then checked the page source, and what did I see? The right, my submitted favicon link commented out, and the default favicon link active just under it.

Did I mess up somewhere? Have I not understood something? Or is it a site bug?

I think the favicons have been disabled for a while, no clue on the current status of that.
