I think I have an idea, about an bug!
As I'm not good at programming and hacking/buging(actually never tried it :D) games or systems, I post the idea here in DO talk! :)
Maybe it's a existing bug or maybe something new, but - some one who is good at programming could try to brake DO's "watch video to send your cargo system". See if you can change the time it arrives(make like 6hrs instead of 45mins), or do more videos than 4!
Like I said I'm not sure if this all ready exists(the last seprom/skylab bug left out there) or it's something new, but if it's new try it out guys, cause this way you will be able to make not only seprom, but also promerium, and sell it to get many credits!
I hope I helped, if you got more questions PM.
