* There was a problem with the SOFI exposure countdown, which didn't stop and went on to negative values (as already happened multiple times in past runs). Due to that the time dedicated to observations took longer than expected. The effect seems to be strongest for spectroscopy (up to twice as much time), but also appears for imaging (up to 30% increase).
