I have found some errors when cleaning, I'm not using mods or the cheat menu and it's a new game for this version.

It doesn't seem to break the game, I picked jock at the start and then tweaked some of the stats in the regular options.
The only cheating I have been doing is skipping the secretary game with (set: $total_points to 999)(go-to: "secretary rewards") in the console. My bad if it's in any way related to the error.
EDIT: I found a 2nd issue whilst 'determining clients interests' in the sales job, it doesn't give you an option to proceed, the only functioning button are the notes you can take.
