Ultimaker 3 interrupts print to ask for print core calibration?

[SimonIC 1]

This just happened to me. 

 

The model was printing just fine for a couple of hours already.

 

When I came back to it a few moments later the print had stopped seemingly at random with the message prompt on screen "Printcores not calibrated: Calibrate now/Ignore"

 

I choose ignore and that was it, the print didn't continue. I'm not sure if it even could continue, because at this point the cores had cooled down already and the nozzle was frozen to the model. I had to manually lower the print bed.

 

Has this happend to other people? I don't find it logical to ask for a calibration in the middle of a print?

Never heard about it, that the message comes up during a print job. Should not happen and seems that this is a bug.
