Ok, so with the Investor perk (Speech 70) you can make an investment in different merchants. I've found a lot of them in the game giving up the offer and I've invested in about 5 different merchants so far, however, only the first one that I invested in has ever actually had an increase in money.
Can you only invest in ONE merchant? Has anybody else invested in multiple merchants? I know I can get the next perk up the chain to give everybody more gold overall but that isn't the issue.
Just not sure if this is a bug or a 'feature' for the PS3?
