What does "add the ability to add triggers and activated behaviours" mean and do!?

@igazor THANK YOU!! That's awesome.

About my game freezing: I already know :P Im playing on a hilariously lame laptop. In fact, it ONLY has Sims on it! I had it erased and put the sims on so that it could play as clean as possible. hahah It has its kinks tho!
