Till its not constant 31 days of combat queen at 1220, my devmeme eyes and ears are closed.
Its also obvious. No maturity means that Queen ovis only to get the eggs and nothing else. After shitting eggs for 15 minutes, she can just drop it and wait at LZ. And its technically not disallowed, since only T3s have restriction to do so and Queen is T4 in stats and abilities, while T2 in the evo branch.
