In the "Missions & Quests" forum, there's a thread called "
Storyline missions -- allow those not on or past the battle to enter battlefields! "

If this particular thread is topmost, it will break the sub-forum layout on "English Forums". The "Missions & Quests" subforum will then have a subheader called "missions -- allow...".

If another thread made topmost, the glitch will be gone.
