At revision: 6675 ~ XML parsing SAX error MLF_CIV4ModularLoadingControls.xml: Unable to open primary document entity (file location) Caveman2Cosmos.xsd at line 0, also says when I start game at top, "CvAltRoot.py isn't valid or doesnt contain Civ4.ini file"
I found more error I will post the screenshots of the errors tomorrow, 1 was the same as above but 7 more errors regarding new things added.
Sorry more errors guys..
EDIT: Killer Rabbits really? Attack 9 and 2 moves

These things are all around my starting city, they killed 6 units so far and I only have 25+ turns in!
