Timetravel event can't be complete

Ohaii. I want to start over the timetravel event, because I didn't realise switching households in save would stop it. Is there a way to stop the progress made and retrive it? Thought I would start the event another time, when I had more time but it started active immidiatly, I didn't realise started with household for testbuild en deleted that save when I was done. :")
