I'm having a very strange issue trying to post in one campaign that I'm in. Whenever I try to post in the gameplay thread, it sends me to the preview page instead and doesn't post the reply to the thread. Hitting the submit button just causes it to redo the preview again and again, making it impossible to actually post. But it's only for one specific campaign and only on the gameplay thread.
It's this one right here: Link
Usually that happens when you're posting something that is an exact copy of another post on the same page, though none of the posts on that page look like likely candidates for duplication. (I usually see it on "dot"s on the first page or Perception rolls that have the same bonuses.)
It does seem to be working again now, so I'm not really sure what happened.
