At level 2, you're supposed to have 1 extractor built, and at level 3, 2 built instantly, for free. Sometimes the ability will work, but other times it will not. I have a replay of when this occurred, if you'd like to see it.
And if you're going to look at this to see if it needs a fix....could we also up the bonus from 0,1,2 extractors to 1,2,4
. Just a thought.
I have an odd feeling I'm going to back and see I missed something, but this isn't the first time I've notice this happen, so I figured I'd mention it. See if anyone else is seeing the same thing.
