1. The wonder "Famen Temple" makes your missionaries always successfull. A small bug in the text messages, when a religion spread would fail, then it is first showed "Your missionary failed.." and afterwards "Hinduism has spread..."
2. AI workers with the same cycles from the normal civ IV: first farm, then workshop, then farm on the same tile... My example has one building a cottage over some grains, another farming a forest nearby, and the third burning a second forest without ressources (no hammers from burning, right?)
3. When using viewpoints, occasionally the resources and improvements are drawn higher on the map.
4. Not a bug, but is there any reason not to build all the religions I get in my capital, since the prophets create holy cities?
