Is this a bug, am I banned or intended?

(Dont mind the ugly icons at top, I've already reported this lol)

Edit: oh wait, the ugly icons is probably why the like icon disappeared.. anyone having this issue too?

If you see "fancy" emoji icons on the site header (hourglass, envelope, bell), instead of the normal icons,
It means one of the JavaScript/Css files of the site failed to load, and it won't work properly.

(This mostly happened to me in the past, when the site took forever to load.)

Just refresh the page until it loads correctly.

Thanks for the report. We were loading the icons from an external CDN that was not behaving as expected - this should hopefully be fixed now.
