Error after loading sims4 game
That error is a current known issue. It's often if not always tied to an event happening at the lot in question, whether your sims are traveling to an event or they're already at a location where one is taking place. Feel free to post in the master thread, and keep an eye on it for updates:
One workaround is to not travel to that lot, if applicable. If you're having trouble loading the save in the first place, try loading a different household instead. If it works, you can invite the affected sims over, or to a different lot, and switch to them; or you can play the other household until the event should be over, then switch back to the original one.
Finally, changing the lot type to something else should end the event there; then you can change it back if you want.
