Not sure if this is a bug or a feature -- sent an explorer last night wearing Formal Wear (for the Luck bonus), and when I checked on him this morning he'd changed into Sturdy Raider Armor, which I assume he picked up somewhere along the way. There is a set Formal Wear in his inventory, so I wasn't sure if there was some "feature" that caused him to switch outfits. Was this supposed to happen?
