I don't know if this has been noted before or not, but I built the Temple of Artemis in one of my cities (not my capitol). A few turns later I noticed that not all of the cities' borders expanded on the same turn; some took another turn. I guess any city that was ahead of Vilcas in the interturn order-of-build didn't get the first 2 culture points until the following turn...
