Two of my sims were frozen (mother teaching son to talk) and the only thing I found that fixed this was getting the family to move house.
After doing this I can't seem to get into buy or build mode. It tells me I can't do so while in the process of moving, but I've waited almost a week now!
It wouldn't be such a problem if I didn't have a toddler, but I at least need to access a crib for him to sleep in!!
Plus, it won't let me call for sevices, eg. a babysitter when my sims are at work.
Help?
