Returned to Lukash with his machine but there is no dialogue about the machine; only, do you have a job and a no job available answer. Every step listed on the PDA except the last which is the delivery task has been completed. There was a red marker; next to the task but it disappeared when I clicked on it and supplied no additional information. This is my third time through the game. I went back over the whole game after completing it the second time. I re-killed all the bandits and Monolith that respawned, found some hidden items and did a lot of artifact hunting. All I had left to do was the Lukash assignment and to go to the Bar to sell all my stuff. I do not think that my replay over already completed game sections should count as freeplay. I have not found any freeplay mode. If there were one; there would be additional tasks instead of every assignment giver repeating the old tasks or saying something loike have a nice day.
