Welcome to the Forum, RockinRobin!
You may be the only one here who has gotten the Mummy's Curse. Thanks for sharing the info with everyone. I haven't encountered a mummy yet, but I know I'll have to soon. I'll have to let a Sim die from the curse, too, just so we'll be able to know what happens. Not going to like that very much!
My sim has also gotten a Mummy Curse. He's a daredevil and brave and yet he was still scared! So funny. Anyways...You have 14 days to live, unless you do one thing off the long list of cures. I decided the best way to go was to visit the Sphinx. He was pretty miserable throughout the whole journey, but in the end he was cured, AND got a soulpeace and various gems (worth a ton of $), AND completed another tomb (which helped with his lifetime wish of exploring 6 tombs in each location). Overall not such a bad thing.
