I'm currently farming karma in GooCore. I cobbled together a little script to collect the chess set, both alabaster and onyx pieces, from the cargo shorts. I decided to use my display case to house the collected pieces and also keep track of my progress. I don't do any testing for the display case, so if you don't have one, this script will probably fail. It's not rocket science, but I thought I'd share it. I have successfully collected chess sets for all my chars now. Here it is - CargoChess.ash:
