I've done all quest except for the one for Dr. 8, because my science is 48 and I need one more level to boost it with a magazine to 75 to complete the quest. Problem is, the only other quest I have left is the main quest at the last stage and every option in the conversation turns Dr. Klein hostile (even when 3 of his collegues try to reason with him) . The other speech checks are too hard. I've also noticed that all enemies have stopped spawning? Is there any way I can gain a level because I can't do the one quest because of the other and vice versa? Thanks
