I didn't see the trackable in the cache today. You can mark it as missing.
Marking a trackable as missing doesn't mess with it's mission or where it as been, it simply removes the trackable from the geocaches inventory. Doing this will get it out of the inventory so future visitors to the geocache won't be looking for it. When the trackable shows up again it will simply continue along it's way.
