I think that the sketchy investment bank is being sketchier than it's supposed to be. I was the 7th, 8th, and 10th person to invest in the current round; 300 then 200 then 100. Right after my investment as the 10th person the same person invested in for spots 11-46, but I've only ever had the first investments gold paid back even though all 3 of mine are marked as paid for 10ish hours. I still have less gold than I started with after mining quite a few times without buying anything else. Maybe I just lack some understanding to how the system is supposed to work, but I think there is something wrong.
