So I finally got to play Back to the Future and I enjoyed almost every minute of it. I'm currently at the cabin in episode 5. Only one catch - I do not have the bug plant. After recording the phone call I put it back because I thought I might have to use it one more time there. That never happend and I simply forgot it there.
Now I do not have a savegame BEFORE the cabin. Is there any way to resolve this problem OTHER than starting all over again?
