You mean first house?
If so, nope, never was. I never experience any problems with the card quests.
1. Yup, most things that are repeated have randoms in it.
2. breakfast has a bug where only one view of the peeking is scene and a scene will not trigger also, if memory serves right
3. Nope Im taking about Sarah and other side quest girls.
I think I posted this on my discord for house events but as for time schedule in the town, I havent bothered to check that, mainly because it is to tedious to check. But from what you mention, there is a few more with various people including your male friends at different places. Honestly bro, I barely check town.
Please use the forum search next time, I answered this many times before, has nothing to do with the mod. This is due to the dev changing Brenda home location and mixing up a few things. I personally, never experience the bug. And this is me using the game with the cheat mod all the time.
I could be wrong but I think it is fixed by either going to her correct home location and not the DownTown South thingy. Or when you enter her new house, exit and renter.
