I had the same issue, save I had in 1.2.3 save had addiction and removing with code I still could not work at brothel. Which to me is an oxymoron, character has cum addiction and they CAN"T whore themselves out. You would think it would be encouraged instead. Started a new game b/c of issue and ran into the flour bug, he never asks you so you can't ever trigger scene with the shop keep. You can just continue on without and get punished daily, other than that the only way I could fix it was to start a new game in 1.2.3 until after he asked for flour then opened save in 1.3 and it worked.
I also ran across another bug but wasn't able to get that far in new game I started in 1.2.3 to test if it came up in the new game. The other bug I ran across was when the old man asks you to wash his back for the first time. After he asked to get the sponge and dialog boxes disappeared character was just frozen and she would just stand facing the closed curtain and could not move at all, I had to close and restart game and skip event.
P.s. Also the Miss Debbie bug, says to follow her. Scene doesn't seem to trigger until you go into the brothel (i.e. you can be working at the brothel and spend all your energy and you have to leave and go back into brothel to trigger) scene shows Debbie saying the guards will lock behind her and she walks out the front door, after that you are spawned outside of the brothel with no one to follow or any additional details of where she may have gone.
