-Electric shuttles, lightning turrets, and lightning/armored missiles are no longer immune to force fields.
I've found this rather nerfs lightning missiles to being almost useless, since one of the main uses I found for them is to take out a stack of ships underneath a forcefield that was otherwise impossible to destroy due to the defenses underneath them rather slaughtering your bombers.
It also eliminates a lot of my usage of them as well in relation to starships. Since the only time I use them against starships is when they're "undisturbed", and often (due to playing against serious turtling AIs), they're under forcefields as well. I find the range of the missile is too small to attack them reliably when they're moving, since the cost of a single missile is not worth damaging only a single ship, which is often the case when you target the ship directly (since it tends to explode when it's just moved into range, rather then being over the top of a bunch of them).
Also I'm not sure where it leaves the Armoured Missile too. I only use it at the moment to disturb ships so I can empty some of the ships out of a particularly heavy system. Though previously (before they cost +40 AI to detonate), I've used them to remove particularly annoying things, like cloaking devices in Tech IV planets, particularly obnoxious Ion Cannons (under forcefields of course), and that sort of thing. Given it's damage is the same as a lightning missile, yet it's cost is 20x that it doesn't seem to have much of a use.
If you're worried about people using it to take out AI Data centers, just double the data center's health and knock the missile down to +10 or something so that it takes two to take one down, so the cost balances out, unless the player is lucky and there's two close together.
