Parent post not showing child posts

Not sure if it's just me, but for post #388333 I'm not seeing the bar saying it has child posts. Both post #54125 and post #119369 have it as their parent though.

I haven't come across other posts with this issue, and other parent posts work fine that I have come across.

Fixed it by changing one of the children to have a different parent, then immediately changing it back. I'm guessing it was the result of some sort of server hiccup at just the right time, so it's probably an isolated incident.

Actually, I've seen it happen before. So, I would reckon it's rare, but not completely isolated.

I've come across this once before as well, fairly recently. In my case, it resolved after I made a tag edit (not a parent change) on the child post.

First happened to me yesterday (post #636109). Solved rewriting the same parent name on the child post (blank tag edit, in the end).

I figured I'd put this in here as well. post #161769, indicates it has child posts, but I'm not seeing any other posts besides itself. Nothing comes up on a similar search, and there is no other image like it under this artist.

This can be solved by parenting any post to it, then reverting it. But I've run into broken parent links myself today, so something is definitely up. I'll change the topic because it's clearly not resolved.

Confirming that blank tag edit on child makes the parent see it.
Editing the parent does nothing.
