Earlier today, I made a new post on my guild's forums under the "Guild Only" tag. After submitting the post, the stats on the top of the page showed me as the most recent poster but the new topic didn't actually show up on the forums.

I had a guildie who's filters got all jacked up. Are you seeing any posts under the guild only tag?

Six Demon Bag
Jack Burton: Hey, what more can a guy ask for?
Egg Shen: Oh, a six-demon bag!
Jack Burton: Terrific, a six-demon bag. Sensational. What's in it, Egg?
Egg Shen: Wind, fire, all that kind of thing!

That was the first thing I tried. I also made sure it didn't show up when I set the filters to "All" and tried the "Classic" view. Haven't been able to see it in any of those and no one else that I've talked to has seen my post appear.
