It's an ideology event, the malevolent choice is supposed to give you a mass cap of +10% to ships, however in the event file it is targeted to 'faction' rather than 'ship' as technological choices do. I think that's why it's not giving the bonus to my ships when I choose it. Can anyone else confirm? I highlighted the line that I believe is an error in red below.
