ERROR 102

It seems extremely likely that the error codes nowadays are mostly connected to events somehow. I find that usually is messing things up ingame for me. I dared have a scientist - but he had to retire because I couldn't count on it working. High School events have llama symbol and can't even trigger/work the half-way-ish way they work with the llama symbol issue if there's another holiday event simultaneously. Then the sim got stuck on the lot and you get error codes when trying to switch lot or getting out of there. I thought it was connected to corrupt save file, but that's not feeling likely atm. It must be event connected. This last year sometime events got very messed up and it's been error:y since then. Somewhere it said active careers are risky - well of course, since the events if they are to work.. two generations up in the household there was a detective - that must've been the big issue that led me to think that save was unsaveable. Now I'm in a completely new one and still get these errors, often connected to some event it seems. This really has to get fixed since events are used for so many enriching situations ingame.
