Back in early Diplo, Worthy Cause had the effect of giving credits to the user.  Due to the fact that I didn't have it at that time, I don't have the reference files to look at.  Because EarnResources is an overTimeAction, I'd assume that the original functionality of it was an OTA as well.  More importantly however, is this method (or actually any method) still functional?  This ability is the only one I've ever known to have given a player credits, though if someone figured out how to do it a different way, that's be alright as well.  I'm just looking for a way to give the player credits via a buff.
