Derek, I don't know if you know this, nobody brought it up here though it seems so obvious you can't miss it. There's an easy way to create nearly invincible fighters once you have discovered afv shield generators and small shield generators.
Just create a fighter with a small shield generator (i.e. small phased I, 15 shield points), and then upgrade that fighter. The small shield generator will be replaced by an afv shield generator (i.e. level II, 1200(!) shield points).
Quite an upgrade, don't you think
(this works with armor as well)
I think I noticed some other bugs, but I can't remember them (anyway, they weren't this big
)
Otherwise great mod, keep up the good work!
