Troubles brewin' bugged

[DankyKangSuper]

I'm currently on the quest "Troubles Brewin'" and I believe I ran into a major bug. I'm at the part of the quest where I activate the Javamatic and it breaks down and I'm told to fix the 3 fuses. I've just fixed the fuses and now I'm being told to mix the embiggening ingredients into the Javamatic again. It won't let me remake the ****tail anywhere and I'm on a shared save file so I can't revert my progress.

 

Does anyone have any ideas of a possible fix or is my save file null and void?

Same here, we have the exact issue. We repiared the 3 fuses, talked to Tully and were told to mix another batch and the pencil sharpener is not accepting anything nor does the button on the calculator work. 

This wasn't this way pre 1.0.2 because we were at this step for hours building defenses. Then the patch hit and we finished building, then went to start the mission and can't. 

We are also on a shared world...
