Okay, I just finished testing the reading to children thing again. I'm thinking ErrorTrap must be catching the glitch as it happens and preventing it, or else it was just a once-off problem. I couldn't get it to duplicate with either a toddler or a child, whether I used the tablet or the regular books.
Here are my Script Error logs. There may be some repetition in the files since I reloaded several times. I'd previously played without cheats on, but I had to turn them on to get static motives/be able to move the motive sliders to make the toddlers/children sleepy enough to be read to.
Edit: I added the log link but it replaced it with a bunch of asterisks...
Thanks for the help. And I hope this helps someone else.
Edit again: it keeps editing out my link with asterisks. I'm not really sure what to do about that.
