Thanks Moomo! That's a good mechanic to know for getting around my problem. I agree with you in that it will almost definitely get more refined as the game progresses, just wanted to get some input as it stands now :D
Just a little something that could go a long way: When I select and engineer and then shift-click a certain amount of structures to build, it starts chipping away at each building one at a time. The planned buildings in that engineer's queue show up as a blue placeholder of what the building will be. However, I can't then select another idle engineer and right-click the blue (planned) buildings to start construction. Has this been brought up at all or is there an easy way around it?</
