If possible try to keep the AIP under at 200-220 before you're ready to attack the AIs' home planets. And yes it looks like few Human Rebellion Colonies blew up. AND Zenith Miners don't actually destroy anything but the planet. Not CS, Warp Gate nor guard posts. I haven't noticed anything like that. They just destroy the planet itself and supply and knowledge with it. They can still be nasty if they appear on planets you were going to capture (Golem, ARS, CSG, Titanite). If it destroys the planet you lose 3k knowledge.
