Was wondering if this patch was going to fix the bug involving Lucan Valerius and the Investor perk, according to the patch notes on UESP one of the fixes will be to "fix issue with merchants not receiving the proper additional gold with the Investor perk".
I was unaware that merchants besides Lucan were not receiving the proper additional gold with Investor, as I have invested in 4 other merchants and their gold increased as expected.
Would be very sad to see this bug fixed.
