I am not sure if this is a bug, but I cannot evac from a veteran-difficulty 'liberate a network tower' mission. From what I recall, there was no evac in the vanilla incarnation of this mission, but the mission briefing for the LW2 version said no such thing, indicating instead that the evac would take 1 turn (200% infiltration). However now that I am in the mission with multiple pods engaged and incoming reinforcements, I cannot call for an evac--the option is grayed out when I click on the evac summons icon.
Is this working as intended, or are we supposed to be able to evac?
