I didn't catch when it occurred but it was just recently.  I was almost completely broke spending everything on mines and defenses and then I glanced at the top right and I had 10k credits and 2k each of metal and crystal.  Here are the save files:

Better yet, I finally found the right auto-replay:

I was watching at x8 speed, but it appears to occur somewhere around the 36-minute mark and about the time that I have my ice colony destroyed by pirates.  I'll try and remember to start manually recording these beta games so I don't have to hunt through autos next time, heh.
