I found two bugs.
First is that cat boys/girls don't spawn, at all.
Second is that occasionally, if you are on the service page and then go to the page to hire new employees and then back, And then service a client. The game will occasionally force you to look at another client. (not sure how else to word this one)
that's all I found so far, I'll keep you posted if I find more (assuming I can make enough money to get that far XD)
