I accepted a plant growth study in Kerbin orbit. I did the plant growth, I finalized it, than deorbited and landed the experiment, however upon recovery the mission was not completed. I did that twice, once without any control just with a parachute and heatshield and once with a probe core. Maybe I missed something like I shouldn't finalize after I have 50 eurekas. Hasn't encountered this kind of problem with other types of contracts from any other contract pack.

Need to investigate further.
