This problem is because you have problems with packets src game and client, check if you have 253 in game and client, or check for example this error, in your game have CG_NAZOX = 250 and src client CG_NAZOX = 253, idk but the problems is packet, check 1 for 1, but the systems you add, not defaults
Declare in the header the extern constant initialization.
Assign a value to the constant/variable in the cpp.
Now by #Including the config file, you'll can use the new constant/variable everywhere as u prefer.
You can edit the config value by using TOKEN("") too, with CONFIGs.
