Not sure when it changed, but only noticed it after the last patch. When in a fight, I can no longer transfer from the cloth, Impl, or Social window to the Weapon window (subsections within the wear window). I did not see anything in the latest patch about it so not sure if I simply missed a prior change. If the Weapon window is open when you start the fight, it will stay open, but I cannot switch to it while in a fight.
