Does Pianus even spawn anymore?

Quit perpetuating this.

Left Pianus - 36 hours (the one who dispels to hell)
Right Pianus - 24 hours(the easier of the two)

I hunted Pianus for a long time. These times are fully confirmed. I used to log in every day at 2PM, kill 10-12 of them, log out, come back the next day at 2:30 (to account for the built-in variance). Every few days it worked out that I got both at the same time. See other threads about this subject.

Why?
