Good question, Martin. The buttons are actually gone. The "board" is right next to the "B". I clicked across the entire tool bar.
Some messaging buttons are gone - I can't post pictures or links.

Maybe it's drivers and/or the specific hardware components. It could be tough to fix.

My guess is that it is related to the cache on one of the content delivery network servers, not necessarily a bug with site code.
Yeah, that's what I meant to say, Martin. 
It's great to have you on this little issue! Thanks!

There may be many; but only those who try to post images, and links with custom text will notice.
Probably true. I can get the emojis by making the them with symbols. () But the emoji button is gone. And as mentioned, the button for posting images and links are gone too (critical for the type of games I play). People who don't use these functions will probably not notice a problem.
Are the buttons actually gone or can you just not see them? If you click where they are supposed to be, does anything happen?
