If it is my misunderstanding, I am sorry. I report 2 behaviors who looks like bugs about beta 13.1 for Windows 64 bit.
1) In my environment, "Avg. Recent Earnings" of Salaries maybe be not average but accumulation.
About a idol, "Avg. Recent Earnings" increased from 267,595 yen (in Nov 2018) to 400,677 yen (in Feb 2019), though she did some works of photographs. And it never decrease.
Even in other new game, it is same.
2) When I borrow the first office, though the massage "This floor is rent free" is displayed, it actually costs a rent expense every week.
I am sorry, I can write English little. But I enjoy this game very mach. It is cute and exciting!
