I think I found an interesting bug on 0.20. Admittedly, I was playing a leaked version, but I liked what I saw so far that I went ahead and bought it here.
On the day that the MC falls sick, I ended up in a condition where Maia was in the Hotel Massage Room in the evening, and the game would not allow me to change time, but the MC appeared as if he was asleep in bed, and I could move him anywhere. I went to the Massage Room and massaged Maia, trying to see if that freed anything up, but no luck. Reloading a previous save, I got lucky and did not end up in the same situation again.
I saved the game in that situation if anyone wants to look at it.
