They've supposedly borked it back together:
G'on - I dare ya. 

Then don't just yet.
They pulled another Maxis:

I tried this out last night and it worked great for no reactions, but my Sim* got struck by lightening and has no memory of it at all - just being on fire.
Will this prevent Knowledge Sims from fulfilling their Wants to see hail and get struck by lightening, then? 

*The Sim that was struck was a Popularity Sim and didn't have any Wants of Fears related to it, but it seems she should have a memory token of it...or better yet, perhaps they ought to lose memories after being struck. 

Thank you.  I love to experiment on the lil' bastages.   
 
What most people get wrong when trying this is that they forget to use fast forward to unpause the game.
Unpausing then fast forwarding won't give you 100%.

How to Make Your Sims Glow Blue

This is a glitch that sometimes occurs when you have a Sim drink the Elixir of Life.
It took me a minute to figure out how to make them do it every time.

Step 1: When they are in a Gold or Platinum Mood pause the game then make sure your Sim isn't wearing what you want them to sleep in (i.e. no pajamas or undies - this is important!) and that you have the Elixir in the bedroom (actually last night I had a Sim drink from one downstairs and then go straight to bed upstairs and the same effect still happened so maybe the most important thing is just the order - drink, then sleep but put it in the bedroom to be sure!).

Step 2: Queue up "Drink Elixir", followed immediately by going to bed; clicking on it and choosing "Sleep in Pajamas (or Undies or Naked, as long as your Sim isn't already in it!)".

Step 3: Fast Forward (use the >>> or hit '3' on your keyboard). They'll drink the Elixir then immediately head for bed and spin into the their sleepwear causing the blue glow to stick to them.

To end the effect just have them drink from the elixir again while in gold or platinum. 

If you can't get it to work, you just ain't doing it right. 
I've done this with over 15 Sims, mostly by accident  and it has worked every time.
Got pics if you need proof. 

Now to mess with SimPE for those other cool effects you guys are talking about.
I wonder if you have a Sim 'Scope Room' right as the Sim they are attracted to is getting into bed if the same thing will happen.  Seems like it would be hard to get the timing right.
