Another badass bug in unit stacks is this:
All units get the shield effect from the first unit on top.

So, if you build one sat, with all shields, and the rest are sats without shields:
1) sat#1 gets hit, shields go down
2) sat#1 gets killed.
3) shields return to full and cover the second sat!

You can also get screwed over if you have an old sat first, and your newer ones Last, since the shield points (possibly zero) from the first sat are used for every sat in the group.

We really need to be able to break up Groups of units, and probably force different designs to fly in different stacks.
