I see that currently, it is regarded as a bug that stations don't get encounters.
I would ask that you consider leaving it this way, or warn players upon loading a game that stations being safe isn't intended and may be fixed.
I loved the initial surprise of getting ambushed right away.
Another bug (this is likely vanilla) is that the biters that get sent to your ship are peaceful to a new platform (likely a 'no military targets, no pollutive buildings" thing.)
while a little odd that the ships will fly away, personally I think it's good game design to not make your first ambush too punishing. (especially since some mods make rockets crazy expensive) Maybe disable biter deployment and have the ship leave once the platform hub goes below ~40%
