Sorry for the delay in responding.
Summer is a big time for me to work IRL, I work more than 90 hours per week, and I rarely get a chance to come to the forums during this time.
I know that bugfix doesn't solve all the problems related to paying rent.
But the bug that remains (and that you have) is rather helpful than penalizing for the game (it makes it easier to unlock a CG), so I didn't find it necessary to publish a new bugfix.
It will be fixed in the next update though
