i was cleaning trash in my base on day 20,, and around 18:00, a popup occurred saying 'Invalid Event' as an error, similar to the save errors when an event occurs. I was still able to save and pause however, so I believe this was literally one of the events just not working??? Is this an issue with my setup/installation,, a bug, or intended feature?

I just got invalid event tonight as well and this is on my 2nd playthrough.. curious if a cause was ever found.. Obviously I have no way of knowing what event it was meant to be, all things considered.
