Last mission "brewing" glitched since patch 1.0.3

[jurik]

Hope you are already working on this since i got through update 1.0.3 and 1.0.4 and nothing changed yet.
I am stuck at the mission where i put all the ingredients of the embiggen ****tail and need to brew. As always i saved and started first time (it was 1.0.2)...

It went wrong. My defensive strategy didn't work out. So i started last save and roamed to gather resources to build fortifications (plaiyng all by myself), defeated schmektor, and came back and built defenses.
It's now impossible to start brewing, Tully doesn't interact with me and i can't press the activation button on the calculator.

I am not alone, reddit it's filled with people with the same issue.
PLEASE HELP, i cannot finish the game!!!!
