post bug?

i found a bug i think, someone posted in one of my topics but i can't see that post inside the topic/on the who posted screen, i made a screenshot of what i saw, i hope you can explain me why and how...

Most likely it is a ghost.

ya well its kind of bugging me... i wanted to know what the post said ^_^

If someone deletes his post this might happen, it is a vB bug that it counts more posts, go complaint to them.
