Yeah; Bombardment Shelters (under Defensive Focus) makes your planets immune to Planetary Bombardment. Not only that, but if the AI gets lucky and picks the immunity to the invasion type you've chosen under Invasion Tactics, you're stuck; you can't go back and pick one of the others. What the heck were these developers thinking?? I'm playing a game where I can't subdue the last Drengin planet. It's three legions defeated an attack by three transports. (How can that even be...at >10-to-1 odds!!) Plus it is immune to the bombardment tactic I chose a few turns back. At a time that score leader Krynn is attacking me w/ determination, I can't get clear of this last Drengin outpost. It's tying up way too many of my assets and bending my strategy out of shape. Not a satisfying game experience, considering the poor design feature. In light of this game's long history, it's surprising to keep bumping into bad design features (such as no quick save, only two autosaves, two-to-three times the mouse clicks to manage your planets as Endless Space 2, etc.).
