vampire options

I've never been able to call a ghost from the tombstone alone. I can only ever do it with the book of life, and it's worked for regular Sims and vampires alike. I've sometimes had Sims mourn at a tombstone at night and the ghost happens to come out afterwards, but since I can't repeat it, I'm pretty sure it was a coincidence.

I have wondered why "Build Skill" is sometimes an option for a Sim that's not there and sometimes it isn't. I never associated it with the Sim being a vampire or not. Now I'm curious...is it based only on what your Sim was doing at the time you "left" to follow someone else in the household?

I never noticed that you couldn't direct a Vampire Sim left behind to build skills. I've believe I've had this issue with Sims that weren't Vamps. I don't know if it has something to do with what level they already are, but if I remember correctly, the skills available to choose from were quite limited anyway.
I hate how this is set up in this iteration. I realize that it's difficult for this game engine to control members of the household in two different places, but I wish there was a way to queue up the members you've left behind and have them continue those actions while you are controlling the others. That way, you could go back and forth without ignoring some of them.

Hey folks I removed a couple of comments in here that came across a bit hostile, it's all good if that wasn't the intention but let's try and keep it friendly please.

I've tried games without mods, completely new saves, new vampires, old vampires, cas vampires and sims born as vampires and it doesn't matter what they were doing or where my sims go, my vampires do not have those "normal sims" options. I've tried it with the scientist career where I had a sim go to work on that lot and have the rest of the family working on skills and such but vampires don't have that option for me, other than "bring sim here". I do use MCCC which I find helps with a lot of game issues but it doesn't seem to fix this one either.

If i recall correctly there is a mod that will enable build skill for everyone but I read on the description it says "fix for vampire unable to use build skill options" along the lines, so I would think it's kind of bug though. I never remembered having the problem but i used the said mod so I wouldnt know.
