Hey Bloonein. Sorry that you're having a difficult time. As a tip have you tried to level up your Science? Unfortunately, in 3.1.17 there were cases where the frequency of the mutation needed for the quest was not often enough and that caused some players to reset the game. It's better now but until I rotate the free build to the next one you may have to either raise your stats (Science or Technique) high enough or start a new game. Apologies for the inconvenience!
