Has anyone else found you can't unload a fabricator that was building when you lifted it? Just a bug that I want Uber to know about to help out... I want to know has anyone else seen this bug or if it was a once off (I don't think it was)?
The easiest way to find out if it was a one off or not is to try and recreate it, if you can get it to happen again then submit a bug report here http://pa.lennardf1989.com/Tracker/ (and check to see if anyone else has reported it)
