Hello I have been playing Offworld Trading for a while now, preferring the single-player option, mostly without a competitor which makes for an awesome, relaxing game! However, last night I opted to leave the game running overnight, mostly to see if I could get out of debt, given a long enough time. I woke up to find I had made around 800 000K with the debt level at 60 000K and a stock price of about 220. I started reducing my debt 10 000 at a time which slowly increased my stock price. Then came the bug: I opted to pay off ALL my debt, which normally results in an increase in the stock price - however, this time it plummeted all the way down to 30 instead of rising - and has sat at 30 ever since, despite my company cash standing at 870 000K and zero debt.
I started my next game, which I also ran overnight, I made 2 billion, which suddenly went into a negative value, with a stock value that dropped to 1.
It is possible I am misunderstanding something - but I suspect a bug... Many thanks
That sounds like an overflow bug. If I can reproduce it, I should be able to fix it (or at least clamp the arithmetic). Thanks for reporting it!

Hi Jason
At least you should have fun reproducing it ! Let me know if I can supply other data for you - incidentally, the 2 games mentioned were played with different companies.
Cheers

I found the cause of your two cases. As suspected, they are both integer overflow bugs. Normal integers can hold values in the range of −2,147,483,648 to 2,147,483,647, so it makes sense that your money went negative when it went past $2 billion. The stock price overflows around $800 million because there's an intermediate multiplication by 3 during the stock price calculation. I've changed both places to use 64-bit integers, which have a much larger range of values. Would you like to playtest the new changes so you can report any other values that overflow?
what do I need to do? - btw, I have yet to get an email telling me that somebody replied to my question - hence the delay with me replying...
I do have both tick boxes ticked... maybe tap the shoulder of your sysadmin?
I'll PM you the Beta password. If you find more bugs, post them in this thread. Thanks for helping improve Offworld! P.S. I don't get e-mail notifications, either
Hello Jason - so I started a game and then left it running overnight. The problem seems solved - numbers update correctly as best I can see without my morning coffee !! My only problem now is what to do with my extra claims Screenie attached below.
Thank you for fixing this
Enjoy!
