Well I looked through a few pages and did not see my specific issue, so. When a wasteland traveler returned he had about 4 items. When I hit collect as he was waiting he entered and all of the items were transferred (apparently) into a task " sell 5 outfits or weapons" instead of my storage and it never brought up the progress bar for the task. I only noticed when I looked in the task list and saw it. I had never sold any items and the number matched what he brought back. The other two explorers worked as normal when they returned.
