To recover the ruins i need to have on the planet both the team and the engineers or only the troops are sufficient and i can disband the team?
In my game, i found some ruins and after the xeno team's work was done i disbanded it and sent the engineers, but they didn't recover anything for a long time (a few months, maybe a year). After that i tried sending back the xeno team on the planet and after little time they started to recover facilities...
Since i can't find stated anywhere that i need to have at the same time both the team and the troops, i'm unsure if it was just luck or i've done a mistake to disband the team in the first place...
