Got to day 47. The event that was supposed to happen did happen and seems to be over (no sounds, no radar blimps, etc), but progress-wise event is still on-going (event begun around 2 AM, I got to 8 PM, but pause is glitched and can't save). Is this a bug? Is something supposed to happen?

One of the Arirals can possibly get stuck on an object during this event and can't properly leave after it ends, meaning you are stuck unable to save.
Input "debug scrape" into a console to force end all meta paranoia (what prevents you from saving). Do note that this is a debug command for when you get stuck in a situation like this, stuff can break if you use it in the wrong situations.
