Hi there, I can have a go at some answers:
1) Not sure about glitches, I haven't come across any particular ones related to this pack. I have noticed sims looking at their phones a little more often now, but not so much that I feel the need to mod it out.
2) I have only had the game mention one crush so far, and it was actually my played teen sim who apparently got a crush on the principles daughter during an active school day. Nothing happened with it.
3) It hasn't particularly done anything great for my teens, other than new clothes and buy mode stuff.
I would mention that I haven't yet been to a prom or after school activity. I did attend a couple of career days, which were pretty boring. Attending active school days (I find) is pretty boring. Going to the fair is pretty boring. I do like the photo booth, but it is disappointing because kids can't use it, ditto with the pillow fights.
I'm not one of the people who ever wanted an active high school. I am happy with the pack just for the 'stuff' to be honest, which is the reason I decided to buy the pack on the cheap after it had been out a while.
