Place a module via the editor. Within one of it's init fields, log the value returned from BIS_fnc_getParamValue for a parameter whose default value != 0. It should log a value of 0. Then, log the value when called from the init.sqf script - it should return a non-zero value.
FYI, this only seems to happen when connected to a dedicated server - it doesn't happen when running preview via the mp editor.
