I am not sure if this bug has been brought to light. I currently am playing version 1.4 with the patch. So far I have done every "quest" prior to going into the Haunted Hotel for Therese. These quest I have done includes:
THE PAIN OF BEING MERCURIO
SURF'S UP
Doing all the jobs for Kirkpatrick (A BOUNTY FOR THE HUNTER,JUMPIN' THE BAIL)
Saving the dying girl to later become your ghoul (TRICK OR TREATMENT)
Kill the "eastern vampire" for Bertram Tung's ghoul (THE HUNTED HUNTER)
BLACKMAIL(the part where you black mail the cheater in the hospital)
ORACLE
THINNED BLOOD
DAYDREAM BELIEVER
BLOODY MESS(not yet collected payment)
Then I precede to do
MAIN QUEST: THE GHOST HAUNTS AT MIDNIGHT
MAIN QUEST: SLAUGHTERPIECE
MAIN QUEST: BAD BLOOD
MAIN QUEST: SIBLING RIVALRY
MAIN QUEST: EXPLOSIVE BEGINNING (PART 2)
It is at this point I go to collect the money for Bloody Mess, I enter the apartment collect the money access the computer read on the emails(not doing any college stuff)... then I go back down access the mailbox again and once again collect the money for the SAME quest. Then i get in the cab and move on to downtown.... I know you only receive 150$(x2 is 300$) for this quest but I figured I would address the fact that you can get doubled paid for it not sure if its because of the way I did the quest in the order mentioned above(I believe they are listed in the exact order I did them) or if this bug is due to my Clan being Tremere or history of Tremere being Eldrich Prodigy. I figured I would give a heads up for those who would want this bug to be fixed( those who do not like the slightest "cheating" for lack of better phrasing this)

Well... Thank you for your time? If you need more info feel free to contact me. I dont care if this bug gets fixed one way or another but I do know certain people who would hate this extra "help".
