Martian Invasion? Where are you?!?! Lol

[WarDaddyIV]

Been playing Expert Mode for ages and can't seem to encounter one...what am I doing wrong?

EDIT: I've defeated ALL bosses including the Moon Lord on all my worlds already so that's not it

I'm actually tired of Martian Invasions because i've had so many in my world.
I have a skybridge that goes through the whole world, or most part of it, from one side to the other. I run back and forth with a water candle and a probe will eventually spawn.
Also the wiki says something like:" If you kill the Martian Saucer a probe will 100% spawn."
So i guess that if you manage to get one Invasion then you can just go on a loop of never ending Probes.

The martian probe can be quite rare but it wont spawn if the lunar event is activated
try looking in the space layer they are much more common there also make sure you dont have a stardust dragon minion activated as it will try to destroy the probe.
