The only way to avoid it is to completely turn it off in the mod settings. I have had such bad luck with this event, I have not had a single game where this even doesn't happen by Septober of year 1 and it tends to go a minimum of a year so I turned it off so I can actually use the mod

unneeded event to be srsly, which blocks the mod itself

whats that

It's an event that can last from a few days to multiple years in the mod.
The effects of the event block the majority of the mod's events and visitor ships can no longer land at your spaceport.

Due to it's rather absurd variability in how long it lasts and the mod authors decision (at the time I posted this, it's been a while since I last checked) to make it so you couldn't simply end the event like every other global game condition event in Development Mode... you'll probably see a lot of people mentioning it in older conversations.

As Ruarc Black suggested, it's best to turn it off.
