For reduce memory usage and possibility of MAFs I advice to use this file. Just download and unpack to this directory: Caveman2Cosmo-test2\Caveman2Cosmos\Assets\XML\Civilizations\ Link to file This little xml dissable Ethnic Diveristy units look. Important: patch dont change anything in C2C mechanic nor remove any units. Only affect graphics! File work with SVN 7781 and upcoming v35. I dont tested it on older versions but should work with v34 and even older C2C's.
