No solution, but, having finished the 3 contracts, I collected them, then brought the materials I had to the center, and finally scrapped the ship, and sold the materials obtained, it marked the assignment as terminated, so ok. PS: To collect the various materials for the contracts, never use the yellow bins, but only put them on the truck, which will count them and they remain even if you exit the game, to retract the next time, if you use the yellow bins, often when you return to the game, some of the necessary materials disappear, such as beds, wardrobes, etc... only the ferrous ones remain.

Hi, do you find any fix? because in my ship the same problem :(
