Storyhour update not showing up in the thread last post field

So I updated my storyhour thread several seconds prior to the site giving me a database error. The post shows for me, but when I'm in the storyhour forum itself, the thread doesn't show that there was a recent update. So my question is, does that recent post actually show up for anyone other than me?

Last post here today (09Jan): http://www.enworld.org/forum/showth...anescape-Storyhour-(Updated-09Jan2016)/page16

Using Firefox while logged in:
Forum index shows 'latest post: 3 Jan' for me.
In the thread, I can see your actual latest post from ~6 hours ago.

Using Internet Exploder while logged out:
Same results as above.

So yeah, there's an error; I can see the post, but it doesn't seem to have registered in the forum index.
