This happened the first time at a mission, and no matter what I did to equip them, most would show up naked. One or two might have a gun with no ammo, or their gun but no armor, etc.
I just sent the troops back home and fast forward past the alien activity thinking it was a bug with the mission, but now it is happening again with a new "Alien Activity" mission. Let me know if you want a saved game or for me to test anything.
I am using Windows version, just downloaded last week so should be newest version.
edit:Sorry, just read the read first post, will attach ufoconsole.log shortly.
