Yes, well it was the first course that we had run (both students were staff who needed the course, as we knew we would have teething trouble and didn't want to risk bad publicity due to messing outside customers about), and the instructors had not then learnt all the faults that could occur on the sim. Could only get a lateral mode on the flight directors, so couldn't engage the AP after the engine failure just after wheels off. No problems flying manually on raw data though
Found out after how to get flight directors back. Absolutely agree about possible difficulty keeping up when out of practice, but my partner in the course did fine on the AP even though not really current.
