TOPIC: Missing event in module

This is weird.

We have an event published for 10/13 that has suddenly disappeared from the module, but appears in the calendar and it does link to the event description and to the registration page. In other words, everything works fine, but for some reason the event just doesn't appear in the upcoming events module anymore.

Any suggestions on what's gone wrong here?

Joomla 2.5.24
DTR 2.8.13

Thanks!
