left behind ship special event,

[Grimmrog_SIG]

This event seems to eb broken/unfinished.

The event triggers the follwng possibel rsults:

a fail, where all crewman are dead.

a success where all creman are dead but some (150? social research get granted)

a choice ending, in this the aliens are alive, there is the chance to choose helping them to get rid of their brain parasites, or let them die.
However choosing both of these does nothign, the wreck just disappears and thats all

My experience: <spoiler> Actually, if you help the aliens, later, whenyou meet their empire, you get a positive modifier in diplo relations.</spoiler>

[Grimmrog_SIG]

If that is the case, then it behaves illogically at this point, because I know all races/empires in my galaxy, and therefore the event should name the race/empire.
On the other side, I wonder if this is triggered towards any empire not existign anymore. But thr devs should have a look over this.

I hope y'all don't mind me semi-reviving this but seeing as no one gave a proper answer and I'm sure others will look this up I figured I would. So, I actually got this event very early game (just 20 years in) and I think I've figured out the rewards. If you do nothing, nothing happens I'm pretty sure.

However in early game if you do help them it essentially allows you to skip the whole "beta, gamma, zeta aliens discovery" thing where you have to decipher their language and automatically establishes immediate contact with a random empire you haven't had contact with yet. The event just saves you from tying up an envoy and a lot of time early game, that's all.
