Forum:The Amazing Vanishing Super Mutants

I recently started playing Fallout 3 again, and I've noticed something weird. I've been to a couple of areas that I knew were Super Mutant Encampments, but I found no mutants there. I found a wasteland captive, and all the loot I would have normally found there, but no Super Mutants. Further, I got to the last step of the Big Trouble in Big Town quest, and I opted to defend the town from the attack that was coming, but I waited, and waited, but no squad of Super Mutants ever showed up; As a result, I never got Timebomb's lucky 8 ball. Is this a bug associated with the latest patch? I'm running the game on Windows 7 if that affects it.
