Thank you for noticing the lack of lag.
Gates are the same as blast doors, the buildings are coded so they could be dynamic size but I found it confusing.
Doubleclick units is now in.
I can't fully explain the logic with the harvesting vehicles, but more or less I let lore get in-front of gameplay.
The movement queing is in too, and multiselecting buildings has been previously (shift). A que is a good point, I'll see about it.
Thanks for playing
