After finished 1st mission of campaign 3, next mission is an entended deployment so armory and party swap cannot be used. however after upgrade my templars, i can access armory (empty armory but the button can be clicked) and swap out party members. didn't try in the other mission so idk if it's happen in other mission too.
slayernz - can you provide a campaign / level in which you see this empty armory? I'd love to fix that bug.
era101 - you should not be able to swap out Templar at this point if it is an extended deployment. If the text reads "This squad is on extended deployment and cannot change team members." then you cannot change Templars THIS level (now), but if it reads "This squad is embarking on extended deployment for the next level." it means you will not be able to change Templars NEXT level (after victory). It is trying to warn you in advance. I will change the message to be more clear.
