Just did 3 missions of Starbase royale 2 out of three were completed sucessfully. They were not credited to me. What's up?

What wasn't credited? The money or the completion count? Please see the 'Read me first' post.

you sure on your 5th roll that you didn't fail? this mission has a high lvl of mission failure.

You may have misread the mission, you only get paid if you get 5 completions in a row,not every time you do it.
