Puppet political parties on zero population planet

[Delar]

Puppet political parties on zero population planets.

I think I found a bug with SE4 with the latest patch Version 1.91. What happens I believe is I use food contamination espionage attack on a planet to reduce its population to zero yet the computer retains control of it.

I then later use puppet political parties to try and gain control of the planet. It says I gain success and they brake away to form their own government and at the same time they are "destroyed" but the planet that they occupied is completed deleted from the game.

I've done this numerous times and can reproduce this bug. I don't know if it matters or not but I'm currently at peace and have a military alliance with the computer AI that I do this to.
