What happened?

Um, i’m not quite sure what to do.
I got on EV to check on my horses, and everything seams fine.
However, when i checked on my post about a stud i have up for breedings in the horse classifieds, it says i posted it 3 hours ago.
Um, what?
I was playing a different game with a friend at the time.

When topics get bumped that have no replies they just update the posted time in the sub forum. 

Oh ok, someone must have just bumped it then.
Thank you very much, and sorry for the post. I was a little confused.

No need to be sorry! We're here to answer your questions. I actually learned something new while figuring out the answer, I thought it said who bumped it on all topics, but it only does if the topics have replies!
