was trying out the missions to earn money to buy parts so i took on an easy mission to understand how they worked. i had to test an engine. nice and easy. all the requirements were checked, right altitude, right planet, right speed. it was all there. so everything was checked, there was no indication that the mission was complete or not. i just assumed i completed it so i landed and recovered the ship but when i go to mission control it says the mission isnt complete. long story short: how do i know if the mission is complete even if all the requirements are checked?
