The event choice is supposed to decrease all ship equipment by 10%, however nothing seem to happen.

Possbile fix, change the xml trigger entry in IdeologicalGalacticEventDefs.xml from

<Trigger>
<OnEvent>OnEventChoice</OnEvent>
<Target>
<TargetType>Faction</TargetType>
</Target>
<Lifetime>Target</Lifetime>
<Modifier>
<EffectType>MassCap</EffectType>
<Scope>Global</Scope>
<Target>
<TargetType>Faction</TargetType>
</Target>
<BonusType>Multiplier</BonusType>
<Value>-0.1</Value>
</Modifier>
</Trigger>

to

<Trigger>
<OnEvent>OnEventChoice</OnEvent>
<Target>
<TargetType>Faction</TargetType>
</Target>
<Lifetime>Target</Lifetime>
<Modifier>
<EffectType>MassCap</EffectType>
<Scope>Global</Scope>
<Target>
<TargetType>Ship</TargetType>
</Target>
<BonusType>Multiplier</BonusType>
<Value>0.1</Value>
</Modifier>
</Trigger

*** Note that: i have not been able to test whether this fix actually works because i have not yet had his event occur again.
