The mission briefing for the Clear Data collection mission on the last bullet point states that "Additional Cleaner Data will grant further Cleaner Network progress and can be sold for $25,000." I had just queued up a new fighter jet and was sitting at $7,500 at mission start, and gathering 15 user data was looking pretty good. After the mission completed I still had $7,500, and when I checked the storage at my only base at that stage of the game I did not see it in storage. A note that may or may not be relevant is that I started the mission while running v1.22, and completed the mission on the first time on v1.22. I then had Steam download the update that was queued. After the update to v1.23b I loaded the mission to the last turn and completed the mission again with the same results.
