I see the top two any% speedruns in this game contains "trojan planes" to infect Greenland, without evolving "Trojan Planes 1". How is this possible?

because the Trojan does not need to have "Trojan Planes 1" to have an uncontrolled flight

There's a glitch on the beta version where if you beat the disease once with the planes gene on you'll randomly get them on other playthroughs

Thanks!

But it didn't work?
