I see you using 99.F.1, but you really ought to upgrade to F.3

AVAILABLE are researches you can do. ITEM MISSING are what you meet prerequisites for, but need an actual item.

The REAL clincher here is if you look down Gauss Defenses tree, you will see this:
Gauss Defenses / STR_GAUSS_DEFENSE (30) [ LOOPED ]
Looks like a bug in the rule set, can't do gauss defenses without gauss defenses!
In contrast, running vs F.3 ruleset, shows:
Gauss Defenses / STR_GAUSS_DEFENSE (30)
DEPENDS ON :
{
LASER_DEFENSE / STR_LASER_DEFENSE (30) [ KNOWN ]
Craft Railgun / STR_RAILGUN (80) [ AVAILABLE ]
}
/Gauss Defenses
Much better, eh?
