Objectives complete but game continues

Issue #1089 new
dalerank repo owner created an issue

I'm on the Capua map, I've completed the objectives (pop. 2500, prosp. 10, culture 35, favour 60) but the game just carries on, I was expecting a "Mission Complete!" window... Any idea why this is? Is it a bug or do I have to maintain these levels until a certain date BC? I don't recall this problem on the original game. Any help please, thank you!
