I managed to delete a planet, mid game. This was not expected.
I had an extra colony ship, loaded with critters or people or pigmies or whatever. Nothing left to colonize so I was just going to decommission it on planet with less than full population. I took it to the desired planet, where I then was trying to figure out how to accomplish said goal.
Most ships you can double click to get to the options for it (upgrade, decommission, etc). But since it was on a planet, this wasn't an option. So I clicked its little icon and hit the delete key. A popup asked if I wanted to delete the ship. I accepted and it deleted the planet. The ship was still there. The popup did specify the ship, not the planet. And it also used the word 'delete' not 'decommission'.
Is this a known thing? If only the insert key would create planets for me, then I'd be set.
Ver 1.96. First game after fresh reinstall.
