I've put two save games up, only difference is in one of them the dividends have already been paid - but in both saves the price of the stock is already crazy (and positive). Third one is much older, it was closer to when price blowed up (overflow?)
I've checked the most recent backup before the price went crazy [which is not one of the uploaded ones], here are the main differences:
Save differences:- [+] Spoiler
- Destroyed the main pirate base and one or two pirate outposts
- Found and sold to The Blackmarket
- The ruins of an ancient war
- A world devasted by a war
- The home of an alien claiming to be a God
Further info:- [+] Spoiler
- Stock price was initially negative, and then turned positive after, maybe, I found SHI secret base and sold that info to a competitor. Not sure though.
EDIT: Also, you might notice that Eridiani Explorations stock price is 0. It has been like that since the start (and on other saves too), I'm not sure if that's intended.
