I was not able to replicate the bug in the asylum again since it only happened once. But there was no character there in her place. Just nobody so I had to end the hunt.
On a separate note, I found another bug. In the house, if you have caught less tall lady and see her running around the house, if you press x to interact with her, her animation gets interrupted and she turns into the blue hair girl (that follows you around the house) and then the game freezes. I did it multiple times and you have to exit the game.
As for financial support, let me know what itch says. I would happily buy all the updated versions of the game but you might consider another platform like patreon for people to donate to you instead.
