I apologize if this was asked before, but I can't seems to find a straight answer even after Googling it.
How exactly does the Shrewd trait work?
I know that it says your Sim(s) will receive 5% of the household fund once a week as interest.
However, when is it paid? I've seem people saying it should be the same week day (In sims day) every time.
On my household A, both Sims have the Shrewd trait. Yesterday (Real time) I recall seeing the notification for the husband on the Sunday, while for the wife it was on Wednesday (Probably match the time they "unlocked" the trait). When I started my game today, I played from Saturday to Tuesday (Sims time) but still no notification at all regarding the deposit.
Also, at one point yesterday I received the notification for the deposit of Household A, while I was playing a different household.
Is it a bug, or part of the mechanic I don't understand.
EDIT : For same Household A mentioned above, the husband just received his interest on Thursday (Sims day), so it is definitely not based on a specific sims day
