Yeah, I'm still having the same issue, and I also get the space rock bug. However, regarding the rock bug...
Weird thing. I was mining last night and found 3 rocks, and he was able to analyze them. So I'm guessing if you just find them you can't, but if you mine them you can?
I can confirm this is correct, one of my sims was able to do the same. I'm now curious to see if the dog I'm currently playing with can hunt for them, and I have the feeling the answer's yes though I suppose analyzing them is another story - the next time I get into the game I'll find out. I'd imagine the same would go for werewolves but I won't be able to confirm that for a little while. Hopefully this will be resolved sooner rather than later for those of us who don't plan to get Seasons.
On the bright side my game is running more smoothly than it has in a long time, which I attribute to the ability to disable memories. It's very nice not to get a message saying "So-and-so went to the park!" while seeing all the townie and NPCs in the area also get little icons above their heads for what's probably the same memory, taking up valuable space, thereby making activities that should only take less than one sim hour take several.
