I am not opposed to using mods, I use several nraas mods in my game already so I will check it out. What I have been doing is making them go to uni doing the work but dropping out before they get their report card, then back in town using the lifetime wish honorary degree to get them the degree. I found if I waited to see if graduation would work they earnt their degree, so when back in town I would have to give them a different degree to what they studied to use the ltw. The mod sounds so much easier to be honest, which might make things actually fun again, instead of having to use testingcheats just to get enough point to purchase the wish anyway.
So I am not at all savvy with tech so all I know if once the glitch happens, uninstalling everything and reinstalling does fix it for a time. Since it first appeared the fix is only temporary and get shorter. So yeah I am totally stumped as to why is happens like this, i tried researching but to no avail.
