Most events seem to decay over time, but some, like the Freedom of information Act, Airport Expansion, and Fracking event seem to be permanent and stack indefinitely. Is this intentional? In the long run, it seems to me, you could currently 100% the happiness of a few groups simply by way of such stackable events, while otherwise utterly tanking their opinions. Or on the flipside, you could run into unsolvable anger issues by selecting a policy over and over again, which will make a particular group hate you, even though you already do virtually everything you possibly could to placate them.
Has this been resolved?
