Please close the gates behind you.

Anecdotally this seems to happen to me more often on blue than the others. Multiple games in a row trying to change the narrative for blue, but it's the same story. Back to back matches on blue with early infiltration due to gates being wide open even airlocked ones had both open and no time to triple airlock while still building the rest of the walls. Next game on red, instant win with a secured base.
