Spring RTS Engine

Ok,

I build 1 stationary and 1 mobile anti missile system, load them all up with 3 anti missiles, get ready for the inevitable missile launch. When it does come several minutes later, the anti missile systems do nothing. Huh? Note that the anti systems were at the edge of my base, and should have had time to intercept.

I just lost a game over this, so any help will be appreciated. (or is this a bug?)

The nuke was aimed inside the protection circle(s)?

It overflew the protection circle.

antinukes only intercept missiles headed within their ranges
for full protection, cover every inch with anti's

This is actually a very enlightening question, since if you weren't an OTA player you probably would assume that shields (anti-plasma) and anti-nukes have a similar defensive abilities.
