Hello.
I have been playing the game for ~a week, ~25 hours. It was a big moment when I realized I could be grabbing the two first nodes within the first minute with engineers, before creeps had spawned. Today I figured I could grab even three. It is rather slim margin but definitely repeatable. Wondered if it is common knowledge (could't find anything relevant with search) or something that is not supposed to happen?
