Haven's Fall, achivement problem/question

[Rulke]

Greetings,

So this is the 2nd time Ive beaten this mission on hard trying to get the achivement "house call" Ive saved 6+ colonies but when I finish the game my totals show only 4. Any idea as so why this is? Am I missing something? Do i have to save the first 5? Or save the first 5 then complete the mission before a 6th comes up? This is crazy easy but I dont know why I'm not getting credit for it. Annoying ><

there are only 5 colonies, you can't let any fall at all and you do this by destroying the spitter thingy before it spawns. The way you do this is just pump out vikings like crazy off the start, and you need to be quick so you can get enough to save the first colony. Just keep massing vikings, send em over to clear the air units then drop them all on in the middle of the colony to clean up. Do this any time one comes under attack and you'll be fine.

Ah, I was letting the first colony go so I could take that extra time to mass Vikings. Changed my build a bit and got it this time. Thanks.
