I know I'm reviving this thread, but I found a weird glitch when tutoring children for school, and I figure this is better then starting a new thread.
I had a teen who had been caught pranking the school, and was thusly grounded. I wanted her father (who's going for Supermax Logic in my Dynasty) to tutor her, since she hadn't been to school yet, and he needed the tutoring hours. (And I figured it was completely in character to have her father plunk her down at the table for extra lessons.)
The option to tutor her was there, under friendly, but every time I tried, the game came up with the pop-up of 'you can't do that, you're grounded' (I'm paraphrasing, as I don't remember exactly).
I had to have him un-ground her to be able to tutor her.
Has anyone else run into this?
