Due to the nature of my problem, possible minor spoilers ahead.
Edit For some reason, I didn't connect that the thread 'Hit The Pipe' was actually my problem so I suppose this thread should be deleted now. Looks like my only option is to start the game again.
So I was massively stuck in one puzzle of the game where you have to obtain the bootleg alcohol from the soup kitchen. Now I have the back kitchen door propped open and everything and tell Cue Ball to add spice to the soup so that he gets up and moves the rack containing the bootleg alcohol, however I became stuck at what to do next.
I eventually watched a youtube clip on how to solve that puzzle and was surprised to see a cutscene of Cue Ball, banging the red pipe causing the stand with the bootleg alcohol to descend on a lift. I never got this cutscene. Whenever I click on the red pipe while the door is propped open and Cue ball has moved the bootleg alcohol to get to the spice rack, all Marty does is say his 'It looks like they run into the basement' line.
Is this a glitch or do I still need to do something to trigger the cutscene where Cue Ball bangs on the pipes with his gun?
