Duplicate sim - BFBVFS or temporary glitch? [SOLVED]

[sloppyhousewife]

Yesterday, I had a YA stuck on a chair because of a passed out dormie right behind it. He was still unable to get up after the dormie had cleared the path, so I had to use the stuck object remover on him, which nuked him, the chair he sat on and a ceiling lamp. I saved, quit to neighborhood view and reloaded the dorm. Everything seemed okay, the YA stood at the mailbox as expected. I sent him inside to do an assignment. A few seconds later, I saw his wants reroll and noticed a copy of this YA mopping up some puddles outside (the original did his assignment as ordered). Plus, he appeared twice in the family thumbnails.
I quit without saving (which resulted in a CTD) and restarted the game. Same thing: YA at the mailbox, I sent him inside, duplicate sim appeared a few seconds later. This time, I forced an error on the impostor and deleted him. This seems to have done the trick, but I wonder if it's save to keep this YA? I have plans for him, but I'd rather Deleted 2 him than have him bork my neighborhood.

ETA: That's good news, thanks!

This is just a temporary scheduler glitch that happens every now and then as a result of a race condition. Deleting the offending sims tends to resolve the problem without issue, as long as it is caught early and the sim is not allowed to speak to itself.

What happens if the sim speaks to itself?

That will create a tear in the space-time continuum. Obviously it ends in a BFBVFS.

[J. M. Pescado]

Pretty much. Ruptures space-time continuum, destroys universe.

Hopefully not while occupying two separate bodies, though.

Not recently.  Well, there was that teleporter accident, but we fixed that and the space-time continuum is back to normal, pretty much.  (No one really misses those 3 extra planets anyway.)

I think you're delusional.  There's only 6 planets and there's always been 6 planets.   Mercury, Earth, Mars, Saturn, Uranus and Pluto.  True, some people claim that the asteroid belt was once a planet that broke up (or failed to form - warring theories ya know).

Well, that's my story and I'm sticking with it.
