My sims was proposing but his action got stuck so I stopped it and restarted the action, then when I went to get out of the sims 4 it said I couldn't as a sim was proposing at this time, which he wasn't as it had already happened. the reason its saying this is because the old action that got stuck is still "happening". what do I do now, all my progress will be deleted!!
unfortunately, there^s nothing you can do other than shooting down the game and loose your progress.
As you are the second person of reporting this message, I think it would be good to create a bug report for it at the bug forum: https://answers.ea.com/t5/Bug-Reports/bd-p/The-Sims-4-Bugs
