[New Contest: Captura the Moment!]

Figured I'd give it a try.

 

[Cloning Argons?]

I too had this problem. I noticed I had more Argons than I should have had after I built a weapon. Like you, I discounted it and built something else. Next day I come back and the thing is built and I have the same amount I had the previous day. I figured it may have been fixed in the update that came out today so I figured I would test it. I went out to farm out Argon, built another weapon, went to do a mission and the Argon came right back. I hope it gets fixed soon.
