A few things that are probably not hard to fix

1. Libraries don't have a building cap like studies do.

2. Pathfinding around cities is inconsistent. If I have a unit on one side of a city, and click on the opposite side, it will sometimes travel through the city (for free), and sometimes it will decided to spend a couple seasons going around it.

3. In the 'stranded knight' quest, it is not clear to what city the knight needs to return. It wasn't my capital....

4. I can see the units in cities that I have discovered but are well outside fog of war.

I swear this list was longer when I thought about writing it...

Most importantly, though, this version is about 1,00x better than 1.2. Keep up the good work!
