When I clicked "GD" it directed me to the maps and modes board.

This does indeed happen for other boards and is a pretty well-known bug. I have no idea what causes it, but it has been around for a long time.

I went into my notifications and ended up in an entirely different section of Boards. Will this eventually get fixed or do we have to wait until people start posting in the entirely wrong threads because of bugs before we get a fix?

When i click on "Gameplay & Balance" it takes me to GD sometimes. Thats how i learned we had a GD board.
