I started playing as the Babylonians for a while, and came across a few problems. Two minor Sid's Tips bugs: The Edubba has a Sid's Tip which has TXT_KEY error. The Pyramids still have Sid's Tips talking about the government help, not the Stonehenge strategies. Most importantly, I came across a Persian graphical bug where their Immortals appeared to have moved the unit but left the graphic behind. See the screenshot where my bowman are occupying the same square as the Immortals. You'll note that the Persian flag is in the square to the right.
