// test bots (can crash the server on next map!)
//set scr_allow_bots "0"
//set scr_testclients "10"
You need to uncomment those settings - like this:
set scr_allow_bots "0"
set scr_testclients "10"otherwise they are NOT read by the server.
That is true for all settings in the cfgs - unless the setting has a default setting listed as being on or off and you want it that way.
And that server.cfg in the main ? will not be ready by the commandline pointing to the x4 mod - just make sure you have the x4 mod's server.cfg in its mod folder.
