Analysis - freezing/crashing when trying to check into a resort

I just thought I would add that even though the freezing stopped when I changed my Sims careers I still had other freezing problems with IP. My game froze when my Sims were just chilling at the beach because another NPC Sim checked in to a resort. Maybe the other resident Sims who are self employed can also cause a freeze. Just beware of that.
ALSO does anyone know if EA actually looks at these threads??
How can we tell them that their game has a bug and they need to fix it?
