@Thunderbolt : which version are you currently playing? 0.15 improved the obedience check to see if girls work or not, maybe you have 0.14 version or older? Btw if you try to change her work and praise her in case she works well, her obedience checks will be better. Until 0.14 some girls with strong personality could refuse do do certain works, like it happens when they don't do specific sexual acts.
@Luxed : Security has been improved a lot lately, but if you still find it difficult to avoid bad events because of you have too much money, remember that there is a way to keep girls safe and spend gold to lower such factor: close the brothel for a few days and give the girls max upkeep cost, your money will go down quickly and no one will be able to harm your slaves; when your money is no more a heavy factor for threat level, reopen the brothel and set girls upkeeps to a normal level (or not, if you still want to spend a lot).
Trader class has skills which allow MC to sell item for a better price; with very high charisma it becomes a new form of gaining money, since MC becomes able to gain more than he spends when purchasing items at market. It is not a bug, it's probably the best achievement for the Trader class.
@juanito : Unfortunately there's no Mac version yet, I'll ask Goldo about it when he comes back.
@rangaru : gonna post a list of spells for each class later today.
