In the help document linked, it says:
This one, instead of adding or removing a value, it will set a value for the custom parameter.
$gameParty.members()[0].addCParam(paramId/shortName, value)
-But, when I use that scriptcall it actually ADDS a value to the existing parameter value.
So, i think some of the scriptcall commands might be mixed up!
How do i SET a value for the custom parameter, I wonder?
