Nope, the startdedicated starts whatever *build* you have there. Most likely the client build, which currently still has a dedicated *mode*. The output "Dedicated server only build" is probably because you already added my mod. As that replaces the AC#.dll it will output this, but this is not necessarily right for the whole thing you have installed. You can check it in two way: Replace the AC#.dll with the orig one you had before and check if the output is still in there (probably not ) or check if Data/Bundles/ has just one file BlockTextureAtlasesD.
