[Bug?] Sim gets 0 money after hacking

Hi! I don't know if this is actually a bug or if I am playing wrong.

My sim attempted to hack Plumbook after succesfully hacking The Mainframe. When the hacking ended, the sim got 0 money. It is like the 3rd time I try to do the same, with the same disappointing results. This time, however, I noticed that my sim got tense right before finishing the hack (She had some tense moodlets from before, that were outweighed by some focused/happy moodlets, which eventually faded since their duration time was over. This left the tense moodlets leading.) So, I'm wondering if it's normal for an unhappy sim to get no money from their hacks, or if it is a bug.

My sim has level 9 in Programming, and reached the top in her Oracle career. I have no CC/mods installed. My only expansions are Seasons and Realm of Magic.

I'm also attaching a screenshot of the notifications, to show that the Mainframe was hacked, and that the Plumbook hack seems to have ended right (though it gave no money).
