@Dreifels:
When you 'update to the latest the SVN assets' what steps do you take to do so?
the svn folders I have in H:\Civ4 C2C SVN
I rightclick on that folder and check "SVN update", then I get the newest files.
After that, I rename the active playing folder = F:\Civ_4\Beyond the Sword\Mods\Caveman2Cosmos to F:\Civ_4\Beyond the Sword\Mods\###Caveman2Cosmos and copy all folders/files of H:\Civ4 C2C SVN (except folder ".svn") to F:\Civ_4\Beyond the Sword\Mods\Caveman2Cosmos
By this, the working folder alwas is same as the current svn
