I often used to post in a similar thread, but before somebody blasts me for necro-posting, I'll start anew. Did something funny happen in your game today. Tell everybody about it.
I'm running an over-stuffed household, with three different couple adventuring in three different countries. My China couple had a errand to run before leaving. While I was waiting for that to finish, one of the Egyptian couple was offered the 'opportunity' to take a photo of "The Dragon Cave". This was about half an hour, Sims time, before departing. I added her to the travel group, when the time came. As soon as He returned, he got this message: "John Simian cannot complete the opportunity The Dragon Cave because one of the targets is no longer available." This is less than a Sims hour after the offer was made. I can see it when an adventurer returns to a partially finished quest and the one who offered has passed away (they age while we are away) but THIS was ridiculous. At least he found 2 Zodiac Animals while digging around waiting to come home with the rest.
